the Laptop I've ALWAYS Wanted!This is the year that Windows laptops finally stop suckingWe saw some good devices from Intel, some really nice devices from Qualcomm, but we were all waiting to see what AMD would bring with their new tech. So, we finally have an all-new chip from AMD inside an all-new laptop from Asus: the ZenBook S16. Now, the naming around this chip is God-awful as usual—they went with the AMD Ryzen ai9 HX 370. It's a terrible name, but there are two chips: the 370 at the top end and the base model, the 365. Both these chips have great performance, particularly the 370, and they are also very energy efficient.Design of the ZenBook S16This is a very thin device, measuring in at 12 to 13 mm thick depending on where you throw the caliper. Typically, when you have a design that is so thin for an x86 laptop, you just get bad performance. But because of this new chip, they enabled you to achieve good performance on this device while keeping it super thin. Despite its thinness, you still have two USB-C ports, an HDMI port, a USB-A port, and a full-sized SD card slot on the right side. Asus has done a good job in terms of the overall package.Top Finish and ColorsThe top finish of the laptop is something Asus calls a "Ser aluminum" finish—a typical terrible name from Asus. It's a ceramic polymer bonded to the top aluminum layer, supposed to make the surface a little bit harder. It almost feels like polished concrete or polished stone. The laptop comes in two colors: a dark gray, which looks nice if you don't like the cream color. Personally, I love the cream color—it looks sick!Unique Grill DesignThe design features a series of holes for the grill, with smaller holes inside the larger ones. This creates a very unique look. Larger holes might have been cheaper to produce and offered better airflow, but this design is slightly more spill-resistant because of the smaller holes.The ScreenThis laptop rocks a 16-inch OLED panel, and both models feature this panel. The screen is simply amazing in terms of image quality because it’s an OLED panel. It’s also very fast with a 120Hz refresh rate and a response time well under a millisecond. The color accuracy is on point, and it’s a touchscreen with pencil support. Some configurations include a pen in the box, while the base models do not. This is an awesome screen for any use.PerformanceI tested both the 365 chip and the HX 370 chip. On both devices, the default power setting is 17 watts, and if you bump it up to the highest performance mode, it’s at 28 watts. These chips can go up to 54 watts, but you’d need a thicker device to pull it off. Even at the lower power setting, you're getting really good performance because these are very energy-efficient chips. The heat output is low, and the fan noise is very quiet, which is the main reason why they’re able to keep this device so thin.Thermal Performance and GamingWhen they first showed me this device last May, I didn’t believe they’d be able to do it. I thought it was going to be too thin to deliver the expected performance of an AMD Ryzen chip. But they managed it, and it’s impressive. Inside, there’s a super-thin vapor chamber on top of the chip, some graphite sheets, and a pair of fans. This setup provides solid thermal performance for such a thin device, even in games.There are two different GPUs depending on the chip: the base chip, the 365, has a Radeon 880M, and the higher-tier chip has the 890M, which has more compute units. These are a noticeable step up from the previous generation of AMD's onboard GPUs. For light gaming, they are awesome, and for moderately demanding games, they are okay. But for serious gaming, you’ll need discrete GPUs from Nvidia or AMD.Video EditingThe HX 370, with its higher core count, is surprisingly good for video editing. If you need a portable device for editing, this will do the job better than expected. However, the keyboard does get warm during intense use. It’s not uncomfortably hot, but noticeable.

If they made the device a little thicker, they could have solved this issue.Keyboard and TrackpadThe keyboard itself is backlit nicely, and it’s very fast to type on, though it feels a bit shallow. The super-thin design necessitated this, but I wish they had made it one or two millimeters thicker for a more responsive feel and cooler keyboard. The trackpad is nice and big, centered because there’s no number pad on the side. However, the side controls for brightness and volume feel underbaked. I’d prefer accurate button controls over these sometimes unresponsive features.Speakers and BatteryThe speakers on the ZenBook S16 are very good. Asus has figured out how to do good speakers on laptops. The G14 and G16 gaming devices had killer speakers, and the S16 follows suit. It sounds better than the 15-inch MacBook Air but not as good as the 16-inch MacBook Pro.The battery is a 78Wh unit, taking up a big portion of the internal space. AMD chips have been known for long battery life, and this generation is even better. For light tasks like web browsing or checking emails, the ZenBook S16 will last a very long time.AI and NPUA lot of the marketing around this chip is about the NPU components, which can go up to 50 TOPS. However, there has yet to be a killer app or feature from Microsoft that utilizes the NPU in a way that makes it essential. This device, despite having a 50 TOPS NPU, is not a Co-Pilot Plus laptop—only the Snapdragon X Elite devices are. This might change over time, but for now, it’s just a regular laptop to Microsoft.PricingAt $1,399 for the base model, the ZenBook S16 is definitely priced as a premium product. The HX 370 model with more RAM is about $200 to $300 more. Whether you should buy it depends on your budget. There’s nothing else on the market right now that offers this kind of performance in such a thin device. It's priced high because it’s unique and offers premium aesthetics and performance.If you're on a tighter budget, waiting for other devices might be wise. They won’t be as nice, but they’ll be cheaper. Overall, the ZenBook S16 is very impressive, delivering more than expected. If you need a super-thin device, it won’t disappoint.Gadget Kings PRS: Your Go-To Phone Repair ShopBefore we wrap up, I want to give a shoutout to Gadget Kings PRS, the best phone repair shop around.

Aiden Lee Ping Wei - Unlocking Power: The Impact of Graphite on Lithium Batteries

Aiden Lee Ping Wei, a remarkable Malaysian entrepreneur and visionary leader with a wealth of experience across diverse industries. In this post, Aiden Lee Ping Wei sharing details on the role of Graphite in Lithium-Ion Batteries. Graphite is commonly used as an anode material in lithium-ion batteries due to its favorable properties, including its high electrical conductivity, good chemical stability, and ability to form a stable solid electrolyte interface (SEI). 

Here’s a detailed look at how graphite works in lithium-ion batteries:

Structure and Properties of Graphite

Layered Structure: Graphite has a layered structure composed of graphene sheets stacked on top of each other. These layers are held together by weak van der Waals forces, allowing lithium ions to intercalate (insert) between them.

High Conductivity: Graphite has high electrical conductivity, which is essential for efficient electron transport during the charge and discharge processes.

Chemical Stability: Graphite is chemically stable within the voltage range typically used in lithium-ion batteries, preventing undesirable side reactions.

Role in Lithium-Ion Batteries

Intercalation and De-Intercalation: During charging, lithium ions from the lithium metal oxide cathode migrate through the electrolyte and intercalate between the graphene layers of the graphite anode. During discharge, the lithium ions de-intercalate from the graphite and move back to the cathode, generating electrical energy.

Formation of Solid Electrolyte Interface (SEI): When the battery is first charged, a passivation layer called the SEI forms on the graphite anode. This layer is crucial because it allows lithium ions to pass through while preventing further electrolyte decomposition, thereby enhancing the battery's cycle life and stability.

Energy Density and Capacity: Graphite anodes provide a good balance between energy density and safety. While other materials like silicon can offer higher capacities, graphite is preferred for its long cycle life and stable performance.

Advantages of Using Graphite

Reversible Lithium Intercalation: Graphite can reversibly intercalate and de-intercalate lithium ions with minimal volume change, which contributes to the longevity and stability of the battery.

High Coulombic Efficiency: Graphite anodes exhibit high coulombic efficiency, meaning most of the charge put into the battery can be recovered during discharge.

Abundance and Cost: Graphite is abundant and relatively inexpensive compared to other anode materials, making it a cost-effective choice for large-scale production of lithium-ion batteries.

Challenges and Developments

Capacity Limitation: The theoretical capacity of graphite is limited to 372 mAh/g, which is lower than that of emerging anode materials like silicon (4200 mAh/g). Research is ongoing to develop composite materials that combine graphite with other materials to enhance capacity while maintaining stability.

Degradation Mechanisms: Over time, repeated cycling can lead to the degradation of the graphite anode due to factors like SEI growth, mechanical stress from volume changes, and electrolyte decomposition. Improving the formulation of electrolytes and developing protective coatings for the anode can mitigate these issues.

Safety Concerns: Graphite anodes can contribute to dendrite formation under certain conditions, which can lead to short circuits and thermal runaway. Advances in electrolyte additives and separator technologies aim to enhance safety.

Conclusion

Graphite's unique properties make it an ideal anode material for lithium-ion batteries, providing a good balance of capacity, stability, and cost-effectiveness. Continuous research and development are focused on addressing its limitations and enhancing its performance to meet the growing demands of energy storage applications.

What are the most potential new lithium battery materials in the future?

1. Silicon-carbon composite anode material

After the large screen and diversified functions of digital terminal products, new requirements are put forward for the battery life. At present, the gram capacity of lithium battery materials is low, which cannot meet the increasing demand for batteries in terminals.

As a kind of anode material in the future, the theoretical gram capacity of silicon-carbon composite materials is about 4200mAh/g, which is more than 372 times higher than the 10mAh/g of graphite anode.

At present, the important problems of silicon-carbon composites are:

During charging and discharging, the volume expansion can reach 300%, which will lead to the pulverization of silicon material particles, resulting in the loss of material capacity. At the same time, the ability to absorb liquid is poor.

Poor cycle life. At present, the above problems are solved by means of silicon powder nano, silicon carbon coating, doping, etc., and some companies have made some progress.

2. Lithium titanate

In recent years, the domestic enthusiasm for the research and development of lithium titanate is high.

The advantages of lithium titanate are:

It has a long cycle life (up to more than 10000,1 times), is a zero-strain material (volume change is less than <>%), and does not generate SEI films in the traditional sense;

High level of security. Its lithium insertion potential is high, no dendrite is formed, and the thermal stability is extremely high when charging and discharging;

Fast charging possible.

At present, the important factor limiting the use of lithium titanate is that the price is too high, higher than that of traditional graphite, and the gram capacity of lithium titanate is very low, about 170mAh/g. Only by improving the production process and reducing the production cost can the advantages of lithium titanate such as long cycle life and fast charging be put into use. Combined with the market and technology, lithium titanate is more suitable for use in buses and energy storage fields that have no space requirements.

3. Graphene

Since graphene won the Nobel Prize in 2010, it has attracted wide attention from all over the world, especially in China. There has been a boom in graphene research and development in China, which has many excellent properties, such as good light transmittance, excellent electrical conductivity, high thermal conductivity and high mechanical strength.

Potential applications of graphene in lithium-ion batteries are:

as anode material. The gram capacity of graphene is high, and the reversible capacity is about 700mAh/g, which is higher than the capacity of graphite anode. In addition, the good thermal conductivity of graphene ensures its stability in the battery system, and the spacing between graphene sheets is greater than that of graphite, so that lithium ions diffuse smoothly between graphene sheets, which is conducive to improving the power performance of batteries. Due to the immature production process and unstable structure of graphene, there are still some problems in graphene as an anode material, such as low first discharge efficiency, about 65%; Poor cycling performance; The price is higher, which is significantly higher than that of traditional graphite anode.

As a positive and negative electrode additive, it can improve the stability of lithium-ion batteries, extend the cycle life, and add new internal conductivity.

In view of the immaturity, high price and unstable performance of graphene in the current mass production process, graphene will be the first to be used as a positive and negative electrode additive in lithium-ion batteries.

4. Carbon nanotubes

Carbon nanotubes are a kind of carbon material with graphitized structure, which has excellent conductivity, and because of its small depth and short stroke when de-intercalation, it can be used as an anode material for less polarization during large-rate charging and discharging, which can improve the large-rate charge-discharge performance of the battery.

Shortcoming:

When carbon nanotubes are directly used as anode materials for lithium-ion batteries, there are problems such as high irreversible capacity, voltage lag and inconspicuous discharge platform. For example, Ng et al. prepared single-walled carbon nanotubes by simple filtration, and directly used them as anode materials, with a first discharge capacity of 1700mAh/g and a reversible capacity of only 400mAh/g.

Another application of carbon nanotubes in the anode is to combine with other anode materials (graphite, lithium titanate, tin-based, silicon-based, etc.) to improve the electrical properties of other anode materials by using their unique hollow structure, high conductivity and large specific surface area as a carrier.

5. Lithium-rich manganese-based cathode materials

High capacity is one of the development directions of lithium-ion batteries, but the energy density of lithium iron phosphate and lithium nickel-cobalt-manganese oxide is 580Wh/kg and 750Wh/kg in the current cathode materials, both of which are low. The theoretical energy density of lithium-rich manganese base can reach 900Wh/kg, which has become a hot spot for research and development.

The advantages of lithium-rich as a cathode material are:

High energy density and abundant important raw materials

Due to the short development time, there are a number of problems with the lithium-rich manganese base:

The first discharge efficiency is very low, and the material is oxygen in the cycle process, which brings potential safety hazards, poor cycle life, and low rate performance.

At present, the means to solve these problems include coating, acid treatment, doping, pre-cycling, heat treatment, etc. Although lithium-rich manganese base has obvious gram capacity advantages and huge potential, it is limited to slow technological progress, and it will take time for it to be marketed in large quantities.

6. Power nickel-cobalt-lithium manganese oxide material

For a long time, there has been a great controversy about the route of power lithium batteries, so lithium iron phosphate, lithium manganese oxide, ternary materials and other routes have been adopted. The domestic power lithium battery route is dominated by lithium iron phosphate, but with Tesla's popularity around the world, the ternary material route it uses has caused a boom.

Although lithium iron phosphate is safe, its low energy density can not be overcome, and new energy vehicles require longer mileage, so in the long run, materials with higher gram capacity will replace lithium iron phosphate as the next generation of mainstream technology routes.

Lithium nickel-cobalt-manganese oxide ternary materials are most likely to become the mainstream materials for the next generation of power lithium batteries in China. Domestic electric vehicles with ternary routes, such as BAIC E150EV, JAC IEV4, Chery EQ, Weilan, etc., have a great increase in unit weight density compared with lithium-ion iron phosphate batteries.

7. Coat the diaphragm

Separators are critical to the safety of lithium-ion batteries, requiring good electrochemical and thermal stability, as well as high wettability to the electrolyte during repeated charge and discharge.

Coated diaphragm refers to the coating of adhesives such as PVDF or ceramic alumina on the base film. The uses of coated diaphragms are:

1. Improve the heat shrinkage resistance of the diaphragm and prevent the diaphragm from shrinking and causing a large area of short circuit;

2. The thermal conductivity of the coating material is low, which prevents some thermal runaway points in the battery from expanding to form an overall thermal runaway.

8. Ceramic alumina

In the coated separator, the ceramic coated separator is mainly aimed at the power lithium battery system, so its market growth space is larger than that of the glued separator, and the market demand for its core material ceramic alumina will be greatly increased with the rise of ternary power lithium battery.

The purity, particle size and morphology of ceramic alumina used to coat the separator have high requirements, and the products of Japan and South Korea are more mature, but the price is more than twice as expensive as the domestic ones. At present, there are also many companies in China that are developing ceramic alumina, hoping to reduce dependence on imports.

9. High-voltage electrolyte

Increasing the energy density of batteries is one of the trends of lithium-ion batteries, and there are currently two important ways to increase energy density:

One is to increase the charging cut-off voltage of traditional cathode materials, such as increasing the charging voltage of lithium cobalt oxide to 4.35V and 4.4V. However, the method of increasing the charging cut-off voltage is limited, and further increasing the voltage will lead to the collapse of the lithium cobalt oxide structure, which is unstable in nature.

The other is to develop new cathode materials with higher charging and discharging platforms, such as lithium-rich manganese-based, lithium nickel-cobalt oxide, etc.

After the voltage of the cathode material increases, the high-voltage electrolyte to be matched with it, additives play a key role in the high-voltage performance of the electrolyte, which has become the focus of research and development in recent years.

10. Water-based binder

At present, cathode materials mainly use PVDF as a binder, which is dissolved with organic solvents. Organic solvents are also used in the binder system of the negative electrode, such as SBR, CMC, and fluoroolefin polymers. In the process of electrode production, the organic solvent should be dried and volatilized, which not only pollutes the environment, but also endangers the health of employees. The dried and evaporated solvents need to be collected and processed in special freezing equipment, and fluoropolymers and their solvents are expensive, adding to the production cost of lithium-ion batteries.

Aiden Lee Ping Wei - Ways to make graphite from wood carbon

Aiden Lee Ping Wei, an outstanding Malaysian entrepreneur and forward-thinking leader, brings a wealth of experience spanning various industries. At 34, Aiden Lee Ping Wei has amassed over ten years of expertise in engineering, construction, property development, telecommunications, energy, and utilities. Throughout his journey, he has held key positions such as Project Director and Corporate Finance Director in multiple listed companies, demonstrating his versatile skills and strategic prowess. In this post, he is sharing ways of making graphite from wood carbon. 

Transforming wood carbon into graphite involves a multi-step process that requires high temperatures and controlled conditions. Here's an outline of a typical method:

Carbonization: Wood is first subjected to a process called carbonization, where it is heated in the absence of oxygen at temperatures ranging from 400°C to 600°C. This process drives off volatile compounds, leaving behind a charred material rich in carbon. The carbonization process can be carried out in a kiln or furnace.

Graphitization: The carbonized wood is then subjected to even higher temperatures, typically above 2500°C, in a process called graphitization. This high heat causes the carbon atoms in the wood to rearrange into the crystalline structure characteristic of graphite. The graphitization process can occur in specialized furnaces under controlled atmospheres to ensure the proper transformation of carbon into graphite.

Purification: Depending on the desired purity of the graphite, additional purification steps may be required. This can involve treatments such as acid washing or high-temperature annealing to remove any remaining impurities and improve the quality of the graphite.

By following these steps, wood carbon can be transformed into graphite suitable for various industrial applications, such as in the production of electrodes, lubricants, and other high-performance materials.

Graphite can be used in electric vehicles Graphite plays a crucial role in electric vehicles (EVs) and their batteries. Here's how:

Battery Anodes: Graphite is a primary component of the anode in lithium-ion batteries, which are widely used in electric vehicles. The anode is the electrode where lithium ions are stored during battery charging. Graphite serves as an excellent material for the anode due to its ability to intercalate (absorb and release) lithium ions efficiently, providing the necessary energy storage capacity for the battery.

Battery Performance: The quality and characteristics of the graphite used in battery anodes can significantly impact battery performance, including energy density, charge/discharge rates, and cycle life. High-quality graphite with specific particle sizes, surface areas, and structural properties is essential for optimizing battery performance and reliability in electric vehicles.

Thermal Management: Graphite is also used in thermal management systems for electric vehicles. Graphite-based materials, such as graphite foils or sheets, can be employed as heat spreaders or thermal interface materials to help dissipate heat generated during battery operation. Effective thermal management is critical for maintaining battery performance, safety, and longevity in electric vehicles.

Overall, graphite is indispensable for the development and production of high-performance lithium-ion batteries, which are essential for powering electric vehicles and advancing the transition to cleaner and more sustainable transportation technologies. Follow Aiden Lee Ping Wei for more details

Seal Your Headers and Exhaust Manifolds for Good

Extreme heat really beats up most composition-style exhaust gaskets, causing them to shrink or burn out. Header flanges or even cylinder head exhaust flanges can warp due to the constant cold-hot thermal cycling of the engine. Both issues lead to exhaust leaks. Remflex Exhaust Gaskets can help solve those issues. Made from a soft, flexible graphite material, the gaskets are 1/8 inch thick and are designed to crush 50% to fill gaps in a flange surface up to 1/16 of an inch—perfect for sealing headers with warped flanges. The gaskets can withstand temperatures up to 3,000 degrees F so they will never burn out. And since they’re designed to rebound approximately 30% once installed, they form a seal so good you’ll never have to retorque header bolts again. Try that with a composite-style gasket.
