What is the reason of lithium battery battery drum shell?
What is the reason of lithium battery battery drum shell? Shared by the 18650 lithium ion battery supplier.
The shell features
Lithium, at atomic number 3 and atomic weight of 6.941, is the lightest alkali metal element. To improve safety and voltage, scientists have developed materials such as graphite and lithium cobalt oxide to store lithium atoms. The molecular structure of these materials forms tiny storage lattices at the nanoscale that can be used to store lithium atoms. That way, even if the battery shell breaks and oxygen enters, the molecules are too big to fit into the tiny cells, preventing lithium atoms from coming into contact with oxygen and exploding.
Protection measures
When the lithium battery cell is overcharged to a voltage higher than 4.2v, side effects begin to occur. The higher the overcharge voltage, the higher the risk. When the lithium cell voltage exceeds 4.2v, less than half of the lithium atoms are left in the anode material, and the storage cell often collapses, causing a permanent loss of battery capacity. If the charge continues, the lithium metal will accumulate on the surface of the negative material, since the negative cell is already full of lithium atoms. These lithium atoms grow dendritic crystals from the negative surface toward the lithium ions. These lithium metal crystals will pass through the diaphragm paper, short-circuiting the anode and cathode. Sometimes the battery explodes before a short circuit occurs, because in the overcharge process, materials such as electrolyte will crack and produce gas, causing the battery shell or pressure valve to swell and crack, allowing oxygen to enter and react with lithium atoms accumulated on the negative electrode surface, thereby exploding.
Therefore, when charging lithium batteries, the voltage limit must be set, so that the battery life, capacity and safety can be taken into account at the same time. The optimal upper limit of charging voltage is 4.2v. Lithium cell discharge also have a lower voltage limit. When the cell voltage falls below 2.4v, some of the material begins to be destroyed. And because the battery will self-discharge, the longer it is put, the lower the voltage will be. Therefore, it is better not to stop at 2.4v when discharging. During the period from 3.0v to 2.4v, lithium batteries release only about 3% of the battery capacity. Therefore, 3.0v is an ideal discharge cut-off voltage. Charge and discharge, in addition to the voltage limit, the current limit is also necessary. When the current is too high, the lithium ions don't have time to get into the cell and will accumulate on the surface of the material.
When these lithium ions gain electrons, they create crystals of lithium atoms on the material's surface, which, like overcharging, can be dangerous. In case the battery case breaks, it will explode. Therefore, the protection of lithium ion battery, at least include: charging voltage upper limit, discharge voltage lower limit, and current upper limit three. In general, in addition to the lithium battery core, there will be a protective plate, which mainly provides the three protection. However, the protection plate of the three protection is obviously not enough, the global lithium battery explosion incidents are still frequent. To ensure the safety of the battery system, the cause of battery explosion must be analyzed more carefully.

The development of lithium ion batteries
The development of lithium ion batteries shared by vacuum cleaner lithium ion battery manufacturer.
In the 1970s exxon's m.s. hittingham made the first lithium-ion batteries using titanium sulfide as a anode and lithium as a cathode.
In 1980, j. Goodenough discovered that lithium cobalt oxide could be used as a positive electrode for lithium-ion batteries.
In 1982 r.r. garwal and j.r. salman of the Illinois Institute of Technology found that lithium ions have the properties of being embedded in graphite, a process that is rapid and reversible. At the same time, lithium batteries made of lithium metal have drawn much attention to their safety risks. Therefore, people try to make rechargeable batteries by using the properties of lithium ion embedded in graphite. The first available lithium ion graphite electrode was trialled by bell LABS.
In 1983, m. hackeray and j. goodenough et al. found that manganese spinel was an excellent anode material with low price, stability and excellent electric and lithium conductivity. Its decomposition temperature is high, and oxidation is far lower than lithium cobalt oxide, even if there is a short circuit, overcharge, also can avoid the risk of combustion, explosion.
In 1989, a. a. thiram and j. g. guddenough found that using the positive electrode of the polymerized anions produced higher voltages.
1991 SONY corp. released the first commercial lithium-ion battery. Then lithium-ion batteries revolutionised consumer electronics.
In 1996, Padhi and Goodenough found that phosphate with olivine structure, such as lithium iron phosphate (LiFePO4), has more advantages than traditional anode materials, so it has become the mainstream anode materials.
With the wide use of digital products such as mobile phones and laptops, lithium ion batteries have been widely used in such products with excellent performance, and are gradually developing to other product application fields.
In 1998, tianjin power research institute began to produce lithium ion batteries commercially.
On July 15, 2018, a special carbon-negative material for high-capacity high-density lithium battery with pure carbon as the main component was released in the research institute of coal chemistry of keda. The lithium battery made of this new material can achieve a range of more than 600 kilometers.
In October 2018, the research group of professor liang jiajie and professor Chen yongsheng of nankai university cooperated with the research group of lai chao of jiangsu normal university to successfully prepare silver nanowires with multi-stage structure -- graphene 3d porous carrier and load lithium metal as composite negative electrode material. This carrier can inhibit the generation of lithium dendrites, so as to achieve ultra-high speed battery charging, which is expected to greatly extend the "life" of lithium batteries. The research is published in the latest issue of advanced materials.

[Lithium ion battery for sale]Lithium ion battery is discussed
Lithium battery is discussed
Power tool lithium ion battery supplier shares that"Lithium battery" is a kind of battery with lithium metal or lithium alloy as negative electrode material and non-aqueous electrolyte solution. In 1912, lithium metal batteries were first proposed and studied by Gilbert n. Lewis. In the 1970s, M. S. Whittingham proposed and began to study lithium-ion batteries. Due to the very lively chemical properties of lithium metal, the processing, preservation and use of lithium metal have very high requirements for the environment. With the development of science and technology, lithium battery has become the mainstream.
Lithium batteries can be roughly divided into two categories: lithium metal batteries and lithium ion batteries. Lithium-ion batteries do not contain metallic lithium and are rechargeable. The fifth generation of rechargeable lithium metal battery was born in 1996. Its safety, specific capacity, self-discharge rate and performance/price ratio are all better than lithium ion battery. Because of its own high technology requirements, only a few companies in a few countries now produce the lithium metal battery.
In October 2018, professor liang jiajie and professor Chen yongsheng of nankai university cooperated with the lai chao research group of jiangsu normal university to successfully prepare a graphene three-dimensional porous carrier, which can realize ultra-high-speed battery charging and is expected to significantly extend the "life" of lithium batteries.
