When I go to the big alternative energy conferences, people ask me: what’s the most recyclable battery out there? Is it lithium-ion? Lithium-polymer? Lithium-iron-phosphate? No, friends: it’s Home Depot.

Let me explain. Stealing batteries from Home Depot is a renewable source of energy. Wow, I guess that was actually pretty simple. Allow me to expand further: the definition of renewable is that it comes back after it’s gone, right? When you fill the false lining on your jacket with flashlight D-cells, or just stuff a bunch of Evereadys down the back of your pants and constipated-penguin-walk your way off of the show floor while pretending to yell at “your wife” on “your smartphone,” those batteries will be back on the shelves the very next day, like it never even happened.

Unlike solar, too, this energy source is available all the time. In fact, it’s quite a bit easier to harvest this power at night, because the parking-lot security guard has to take his break around then.

Sure, it’s not a perfect solution. Sometimes they move them around, or they put a camera near the batteries. We’re going to need to develop new strategies to extract this energy, and it will take cooperation from everyone in society (for instance, a big guy who can stand around the paint aisle and block the loss-prevention lady.)

Overall, we need to use less energy, because I am getting tired of driving to the store every day just because I had to use an entire shipping crate full of double-A batteries to boost my car. I’m doing my part, by only using solar calculators to compute my profits from selling the excess batteries on Kijiji under the name of a local tough-on-crime politician.

"Hey, the laptop feels weird."

So, Sander's lid isn't closing flush. On closer inspection, the touchpad sure is popping up out of the keyboard by about the same amount as that gap you see in the above picture, so roughly 1/8".

"Ah, fuck." I think to myself. "That's probably a spicy pillow."

So, I flip Sander over and break out my handy-dandy T5 Torx bit to take the bottom of the case off. I ease my way in by working at all of the screws at once. I am careful. I am cautious...

... And I jump 3 feet out of my skin when the plate suddenly releases with a resounding CRACK:

That 1/4" gap you see there? That's not the lid. That's the bottom plate of the laptop, pushed up by the swollen chunk of chemical oh-no underneath it now that there are no screws to keep the delinquent battery subdued. Normally there are sets of clips along the inner edge of the chassis that hold the plate on, but they were no match for the Spicy Pillow.

There he is! Sander Cohen's undoing in all its glory. If you've ever wondered what a 50Wh 3-cell lithium-polymer battery looks like once it's going spicy, now you've seen it! :D

A few hours later and he's now recovering from surgery and doing quite well, though he will forever be tethered to the wall AC now that he's got no cell in there. I'm glad, because I'd just finished wiping the machine clean and setting him up for BabyCat to use for her schoolwork and some games. @_@; Her phone recently shattered (wasn't her fault either, the poor thing) and this was a way of cheering her up, and it almost went so horribly wrong.

E-VOlution: a poll-based interactive fiction

part 1 here!

A helpful little notion in the back of your head says Activate combat protocol?

Sure. Okay. Sounds good.

You act on instinct. Another taser dart whizzes past and you grab the cord out of the air; you yank it hard and pull the security guard off balance. In the same instant you're on your own feet, the stun gun flying into your hand like a yo-yo with another quick jerk of the cord.

A conduit in your palm opens and you grip the stun gun hard, pushing an electrical charge into its battery. It crackles in your hand, the battery swelling into a pillow and threatening to crack its plastic casing. Perfect.

"Catch," you say, and then you throw it at the other security guard at approximately Mach 4.

The stun gun explodes, electricity sizzling through the air and knocking the guards to the floor, motionless save for electrical muscle spasms as molten lithium polymer splatters over them.

"Holy shit!" your friend shouts. "C'mon, let's go!" He grabs your hand, apparently unafraid to touch you even after seeing what you just did, and the two of you keep running. Unfortunately you don't run for long--only a few yards, really.

"Oh--fuck," your friend says as you skid to a halt in front of a big, thick door marked EXIT; he mashes a keypad beside it and nothing happens except blinking red lights. And damn, the sirens are really starting to get on your nerves. "They've locked us in. I can't break this one down."

"I can't nap through this, can I?" you sigh.

"Not this time, buddy. Fuck," he says again. "I--okay, we might be able to hack our way out, but we'd have to stay here and do it and--you might have to fight off more security." He runs a hand through his long, fluffy hair, his chest heaving with exertion and adrenaline. "Or we can try getting out through the service exits, maybe they haven't locked those up yet, they're kinda out of the way, and, and we might be able to avoid more security going through the back but it'll take longer and it's probably locked anyway and--shit, E, you were kinda made for situations like this, right? What do we do?"

Calcium sulphur batteries (uwu)

Okay, so, i've become interested in z-pinch studies for aerospace purposes (i'm really excited about the prospects, everything works on paper, but i naturally want to actually witness p+N14 fusion for above 0.01% of available protons before i go trying to get the materials to build a real liquid fueled SSTO fusion rocket, especially since there are thousands of folks way smarter than me who have presumably thought of this before and we don't have it yet, so yeah). Anyways, if i want the extremely large electricity input without making my electricity bill higher than a whole month's rent and getting my roommates mad at me, i'll need to collect solar or wind in a battery bank. Since lithium batteries are just about all immoral and expensive (yes i am writing this on a device powered by lithium batteries, it would be lovely if capitalists would take a hint and switch to things that just objectively perform better and are cheaper, but whatever), i figured this would be a nice excuse to experiment around with some new battery designs. Since all of them will require sulphur, i won't be able to really get into it before mid may due to some concerns about the smell and risks of getting sulphur powder everywhere (it's very yellow and hard to clean out), but i felt i might as well share my preliminary ideas. First off, in order to make the organic sulphur polymer, i'm looking to explore mostly citrate based polymers, perhaps with phenylalanine mixed in in order to both give more bulk as well as providing nitrogens for sulphenamides to form. Since i'll need urea later, i was also considering partially polymerizing urea with citric acid and adding that into the molten sulphur mix, but i'm less confident in the stability of that and a bit concerned about the potential noxious fumes produced. Regardless, that's the short of the sulphur cathode, details will definitely change after i refind that paper which went over a great way of preventing insoluble polysulphide production. I'm also gonna experiment with anode material and even the ions i use. I know i said "calcium sulphur batteries" in the title, but due to how common aluminium is and how much easier magnesium is to work with (and the fact that their specific energies are higher), i'll also be considering those two. Even beyond that, there are so many potential anode materials, including even amorphous carbon and carbon nitrides which i'd love to test since there's just so much to improve on and i'd rather do a lot of experiments with cheap to make materials and potentially land on a great solution than accept something subpar because it took less effort. Anyways, of the materials i plan on using, there's magnesium sulphate, aluminium sulphate, calcium chloride, potentially other calcium salts (is the salt with taurine soluble in water? IDK, can't find an answer so i'll test it), charcoal, vegetable oil, urea, and phenylalanine. Those may seem like an unrelated hodgepodge of compounds, but they've been chosen because they're what i have/will soon have and they're also all extremely cheap. If the urea works out well in the battery, i may have to make this project a meme and attempt to make a z-pinch device with as much urine as possible (use it to make ammonia for the plasma, to make the batteries, and i'm sure there's some way to use urine in a capacitor (maybe just distilling off the water to use as a dielectric? idk, it's been a while since i tried making a capacitor)).

Anyway, i really didn't expect this long trainwreck of a post to end with discussions of urine, but what can you do? This is all probably nonsensical, even by my standards, but basically i want batteries and i think i can make them cheaper per megajoule of stored energy than the ones i could buy, even accounting for the inevitable failed experiments.

please share with the class the most novel misadventure in good lab conduct you've had to live through. bureacratic or clerical issues included + bonus points if you're implicated

Once upon a time, there was a trio of research assistants. These research assistants worked with alkali metals in their daily life; they knew quite well, of course, that alkali metals react with water (rapidly and violently) and air (slowly, but the oxide created is explosive.)

These research assistants made some Li-metal batteries to test the durability of a certain polymer material under the electromagnetic and physical stress of being in a battery. They took the batteries that shorted back to the wet lab and opened them up to remove the polymer material and see if it had any notable differences to before it was tested. The disassembly went fine (though they had to use a manual file as using a mechanical one would have possibly created a heat enough to have ignited any lithium oxide that was there.) They removed the polymer material and stored it for safekeeping, but now they had a bunch of lithium metal outside of inert atmosphere.

The oldest research assistant wanted to know where the liquid to store the lithium metal was (as in organic solvents lithium generally won't oxidize.) The middle research assistant had fucking had enough after the filing escapades, and gestured vaguely to the back of the lab. The youngest research assistant figured that they'd go look for some mineral oil, since that's the most commonly used liquid to immerse alkali metals in for safekeeping.

However, when the oldest and youngest research assistants looked around the lab, they saw that the mineral oil was out of reach of both of them. (Neither of them was >165cm, you see, and it was on a high shelf.) However, that was fine. There were other organic solvents in the lab, at a much more reasonable height (in the flammables cabinet.) The oldest research assistant looked through the cabinet, but most of them were not in sealed containers- water might have gotten in. In addition, some of them were less than 99% what they were supposed to be, therefore some of that impurity could be water.

The oldest research assistant pulled out one of the few sealed bottles that was 99.9% pure (HPLC grade). They poured some of the liquid into a beaker- enough to cover all the pieces of lithium metal that remained. The liquid, by the way, was 99.9% pure dry methanol.

The two research assistants carefully placed the lithium metal in the beaker in the fume hood. They then proceeded to immediately slam the fume hood sash down.

You see, dear reader, alkali metals don't just react with water. Though that's what you'll see if you read about them online, they actually just really like to form hydroxides. So if something has an OH group attached to it, alkali metals will react. Oftentimes more rapidly than with water!

The lithium chunks were fizzing, hissing, and skidding around on the surface of the water inside the fume hood. Luckily for us, however- I was the youngest research assistant in this scenario- we were working with lithium, the most electronegative and lightest of the alkali metals. Due to this higher electronegativity, it reacts less rapidly with OH groups than the heavier alkali metals do. So there was no explosion, as fun as that might have been with the sash down. The moral of the story is to use your head about chemical interactions, and don't believe everything you read on university EHS websites.

Anyway, the oldest research assistant is working at one of the top universities in the country now. I wish them all the best.

I ask this in all seriousness: would a pickle jar make a good fireproof container for a phone with a battery pillow?

They seal tight and don’t crack like mugs do when I put hot tea in them to chill overnight.

But I’m not sure about what a phone battery needs to burn, and it would be unfortunate if it still burned a house down AND kicked it off with exploding glass. But it would be great if a fireproof container was $3 and came filled with pickles.

I just don’t know enough about chemical fires. And it would not surprise me if my glass jar idea is risky and ill-advised at best. I’m just so impressed by how durable and useful the things have proven to be.

Cleaning out my ask box; thanks for your patience.

I would be worried about any glass container cracking if a battery caught fire inside, even if it's something sold as oven-safe (which pickle jars usually aren't). The battery fire is liable to put a lot of heat into a small area very fast, which is the worst case scenario for thermal expansion stress.

I do have a better suggestion for you than anything in my original post, though: Get a fire bucket, with a lid, and fill it half full of sand. Make a shallow hole in the sand, put the battery in, and cover it with a shallow layer of sand (like half an inch).

You don't need a big fire bucket, but it does need to be something sold as a "fire bucket" or "ash bucket" because that's how you know it's actually tested to hold something burning hot without cracking, melting, or releasing toxic paint breakdown fumes. The sand adds extra heat and shock absorption and an extra layer of protection (after the lid) from any burning liquid splashing out of the bucket.

I'm told that there are also special-purpose plastic bags, made of fireproof polymers, designed specifically to contain lithium ion battery fires, and that these can often be purchased from places that sell remote-controlled car toys and the like. I would not feel safe using one of these without some kind of outer metal container to back it up, because I expect it would get very hot if the battery did catch fire, but this may cut the cost compared to a fire bucket (on the other hand, you can probably reuse the fire bucket for other stuff).

What Are the Important Parts of an Electric Skateboard?

The following are the crucial parts of an electric skateboard. Without these, most e-boards would work. We’ll go over each of these parts now so you have a better idea of their materials.

Deck: The deck is the “board” in “skateboard”. Usually, it’s a single piece made from one or more materials, like maple, bamboo, fiberglass, or carbon fiber. The deck is then covered in grip tape to provide traction for the rider.

Battery: Most electric skateboard batteries are made of lithium-ion. Lithium polymer and LiPro4 batteries are possible but less common. Lithium batteries do need to be treated a certain way both for the sake of extending their lifespan and for safety.

Motor & Controller & Remote Control & Trucks: These accessories for most electric skateboards are made of metal.

Battery box and ESC case: plastic. The ESC shell of some electric skateboards is equipped with metal sheets, which can dissipate heat better than all plastic shells

Skateboard wheels and straps: Electric skateboard and longboard wheels aren’t any different than the usual kind. Most wheels and straps are made of polyurethane material.

Bearings: Bearings generally have two types of metal bearings and ceramic bearings. At present, most electric skateboards use metal bearings.

Some High-End Electronics: Certain laptops, cameras, and even smartphones might incorporate 3s lipo batteries for their slim profile and ability to deliver extended battery life.

Choosing the Right 3s Lipo Battery

Selecting the perfect 3s lipo battery requires considering two key factors:

Battery Capacity (mAh): Measured in milliamp-hours (mAh), the capacity indicates the total amount of electrical charge a battery can store. Higher mAh translates to longer run times for your RC models or drones.

Discharge Rate (C): This rating specifies the maximum current a battery can safely deliver continuously. A higher C-rating signifies the battery's ability to handle bursts of power, crucial for applications requiring quick acceleration or demanding maneuvers.

For instance, a 2200mAh 30C 3s lipo battery offers a capacity of 2200mAh and can deliver a continuous current of 2200mAh x 30C = 66 Amps. This battery would be suitable for RC applications that require a balance of good run time and moderate power output.

Remember, consulting the manufacturer's recommendations for your specific RC model or device is crucial to ensure compatibility and optimal performance.

Essential Care for Long-Lasting 3s Lipo Battery Performance

Just like any other battery, proper care is essential to maximize the lifespan and safety of your 3s lipo battery:

Utilize a Lipo-Specific Charger: Always use a charger specifically designed for lipo batteries. These chargers provide the correct voltage and current to safely charge your battery without the risk of overcharging.

Maintain Proper Storage: When not in use, store your 3s lipo batteries in a cool, dry place with a charge level between 30% and 50%. Extreme temperatures can significantly degrade the battery's performance and lifespan.

Regular Inspections: Regularly inspect your 3s lipo batteries for any signs of damage, such as bloating, punctures, or leaking electrolyte. Damaged batteries pose safety risks and should be properly disposed of.

Invest in a Lipo Bag: For added safety during charging or storage, consider using a fireproof lipo bag. This provides an extra layer of protection in case of unexpected malfunctions.

By following these practices, you can ensure the safe and reliable operation of your 3s lipo battery for years to come.

The Technology Inside: Exploring the Hardware that Powers Our Connections

The hardware of a mobile phone is what truly differentiates one device from another, and understanding these components offers insights into how mobile phones have evolved to become more powerful and efficient. The main hardware components of a mobile phone include the processor, memory, storage, battery, display, and camera, each playing a critical role in the device's functionality.

The processor is the device's heart.

People often refer to the processor, also known as the central processing unit (CPU), as the heart of a mobile phone. It processes instructions from apps and the operating system, performing tasks that allow the phone to function. Early mobile phones contained simple processors sufficient for dialling and text messaging. However, modern smartphones incorporate advanced multi-core processors that can handle complex graphics, high-resolution video streaming, and multitasking with ease.

These processors prioritise efficiency over speed in order to prolong battery life and improve the user experience. To optimise performance and efficiency for their specific devices, companies such as Qualcomm, Apple, and Samsung develop their own processors.

Memory and Storage: Keeping Everything Running

Random Access Memory (RAM) and internal storage are critical for the smooth operation of mobile phones. RAM is the short-term memory that stores the data your phone needs to access quickly, such as the apps you're currently using. As mobile apps have become more complex, the amount of RAM in phones has significantly increased to prevent lag and improve multitasking capabilities.

Storage, on the other hand, is where your phone keeps everything, from your operating system to your photos and apps. Earlier phones had mere megabytes of storage, but today's smartphones come with up to a terabyte of space, thanks to advancements in solid-state storage technology. This evolution has eliminated the need for most users to expand their storage through external means like microSD cards.

Battery: Powering Prolonged Use

The battery is what powers every other component in the phone. Battery technology has had to evolve rapidly to keep up with the increasing power demands of modern smartphones. Initially, mobile phones relied on nickel-cadmium batteries, but the more efficient and environmentally friendly lithium-ion and lithium-polymer batteries swiftly replaced them. These batteries offer a higher energy density and do not suffer from the memory effect that plagued earlier types, allowing for slimmer designs and longer battery life.

With the advent of power-hungry features like GPS, Bluetooth, and high-resolution screens, managing battery life has become a critical aspect of mobile phone design. Manufacturers continuously work on optimising software and hardware to enhance battery efficiency, and features like fast charging and wireless charging have significantly improved user convenience.

Display: The Window to Technology

The display of a mobile phone is perhaps the most noticeable aspect of its hardware. From the early monochrome LCDs to the latest OLED and AMOLED screens, mobile phone displays have seen tremendous growth in quality and functionality. Modern displays offer high resolution, vibrant colours, and dynamic contrast ratios that make viewing a pleasure. Furthermore, touchscreen technology has evolved from resistive touchscreens, which required pressure to function, to capacitive touchscreens, which respond to the lightest touch.

Display technology also incorporates features like high refresh rates and HDR support, enhancing the viewing experience whether you're scrolling through social media, watching videos, or playing games. Innovations such as foldable screens are pushing the boundaries of traditional mobile phone designs, offering new functionalities and challenges.

Camera: Capturing Moments

The camera has become one of the most important components of modern smartphones, evolving from simple tools for capturing grainy images to sophisticated systems that can rival traditional cameras. Early mobile phone cameras were low-resolution and lacked the features necessary for taking high-quality photos. Today, smartphones feature multi-lens camera systems with capabilities such as optical zoom, wide-angle lenses, and advanced image processing algorithms that dramatically improve photo quality.

Advancements in camera technology have also enabled features like night mode, portrait mode, and 4K video recording, making the smartphone camera a critical selling point for manufacturers.

Conclusion

The technology inside mobile phones is a complex interplay of engineering and innovation that has transformed over the years to meet the growing demands of users. Each component, from the processor to the camera, plays a vital role in shaping the functionality and user experience of the device. As technology continues to advance, we can expect even greater enhancements in mobile phone hardware, which will open up new possibilities for how we use these devices in our daily lives.
