What are the advantages of polymer lithium-ion batteries in comparison with lithium-ion batteries?

1. There is no battery leakage problem. The battery does not contain liquid electrolyte and uses colloidal solids. 2. Can be made into a thin battery: with a capacity of 3.6V400mAh, its thickness can be as thin as 0.5mm. 3. The battery can be designed into a variety of shapes. The polymer lithium-ion battery is easier to be thinner in shape, and there is no need to use a metal shield to wrap it, so it is easier to customize into various shapes. 4. The battery can be bent and deformed: the polymer battery can be bent at a maximum of about 900. 5. Can be made into a single high-voltage battery: liquid electrolyte batteries can only be connected in series to obtain high-voltage, polymer batteries. 6. Since there is no liquid, it can be made into a multi-layer combination in a single particle to reach high voltage. 1. Energy density: The greater the energy density, the more capacity the unit volume can have. The energy density of the polymer lithium battery has now reached 600Wh/L+ through the modification of the negative electrode (anode), barrier and other materials/thickness. 7. Security: In extreme environments (for example, overcharge/high temperature), lithium batteries will generate violent chemical reverberations and present a large amount of gas. At this time, liquid lithium batteries are wrapped by a metal shell, so when the internal pressure is quite high, the shell will Fragmentation and explosion will occur, and because polymer lithium battery only recycles packaging aluminum film to hold the package (or plastic shell), as long as the internal pressure is slightly higher, it will expand and may split and will not cause an explosion. But it should be noted that whether liquid lithium batteries or polymer lithium batteries can burn in extreme environments. 8. Cost: In addition to the higher material cost of polymer lithium batteries than liquid lithium batteries, because polymer lithium batteries can be customized at a higher level, more costs will be presented in the process of design and manufacturing, such as various types of customization. The cost of the polymer lithium battery is higher than that of the liquid lithium battery of the shape scale/rule.
