The polymer battery has many obvious advantages such as high energy density, smaller size, ultra-thinness, light weight, high safety and low cost, and is a new type of battery. In terms of shape, lithium polymer batteries are characterized by ultra-thinness, and can be made into batteries of any shape and capacity to meet the needs of various products. The minimum thickness that this type of polymer battery can achieve can be up to 0.5mm.
From the structural point of view, the full name of lithium polymer battery should be lithium ion polymer battery. In this way, lithium polymer battery is actually a kind of lithium ion battery. But the biggest difference between the two is the different electrolytes used inside. Lithium-ion batteries use liquid electrolytes, while polymer lithium-ion batteries use solid polymer electrolytes instead. This polymer can be solid or It is semi-solid (gel-like).
The polymer lithium battery has the following 7 characteristics:
1. No battery leakage problem. The battery does not contain liquid electrolyte and uses colloidal solids.
2. The battery can be bent and deformed: the polymer battery can be bent up to about 900.
3. The capacity will be twice as high as a lithium-ion battery of the same size.
4. It can be made into a single high-voltage battery: liquid electrolyte batteries can only be connected in series to obtain high-voltage, polymer batteries.
5. Can be made into a thin battery: With a capacity of 6V400mAh, its thickness can be as thin as 0.5mm.
6. Since there is no liquid, it can be made into a multi-layer combination in a single particle to achieve high voltage.
7. The battery can be designed in various shapes.
In short, polymer lithium batteries are mainstream in terms of technology and future development, and their characteristics can be described as many advantages.
