Overcharging: When the voltage exceeds 4.2V, the electrolyte decomposes, producing a large amount of gas, causing the battery pressure to increase, lithium precipitation on the surface of the overcharged negative electrode, and the battery explodes.
The shape of polymer lithium batteries can be customized arbitrarily, and ultra-thin batteries can be micro manufactured, such as 0.25mm. Therefore, mobile power supplies with polymer lithium batteries can also be designed to be more flexible in appearance. Many smart wearable devices now use lithium polymer batteries for their batteries.
Polymer lithium battery is a branch developed on the basis of lithium ion battery. What are the classifications of lithium ion battery?
Compared with soft pack lithium batteries and square lithium batteries, cylindrical lithium batteries are currently the ones that are commercialized earlier,
Cylindrical lithium batteries, especially 18650, are among the top three main battery forms due to their unique structural characteristics and standardized models.
Lithium iron phosphate battery refers to a lithium-ion battery with lithium iron phosphate as the positive electrode material. There are various types of positive electrode materials for lithium-ion batteries,
There are two main forms of square low-temperature lithium batteries, one is a hard shell aluminum shell square lithium battery, and the other is an aluminum-plastic film soft pack square lithium battery.
Lithium iron phosphate battery is a new type of lithium-ion chemical battery, consisting of lithium iron phosphate as the positive electrode material, graphite as the negative electrode material, and organic lithium salt as the electrolyte.
