The difference between lithium ion battery and polymer lithium battery
1. The raw materials are different. The raw material of lithium ion batteries is electrolyte (liquid or gel); the raw materials of polymer lithium battery are electrolytes including polymer electrolyte (solid or colloidal) and organic electrolyte.
2. In terms of safety, lithium-ion batteries are simply blasted in a high-temperature and high-pressure environment; polymer lithium batteries use aluminum plastic film as the outer shell, and when organic electrolytes are used inside, they will not blast even if the liquid is hot.
3. With different shapes, polymer batteries can be thinned, arbitrarily shaped, and arbitrarily shaped. The reason is that the electrolyte can be solid or colloidal rather than liquid. Lithium batteries use electrolyte, which requires a solid shell. The secondary packaging contains the electrolyte.
4. The battery cell voltage is different. Because polymer batteries use polymer materials, they can be made into a multi-layer combination to reach high voltage, while the nominal capacity of lithium battery cells is 3.6V. Voltage, you need to connect multiple cells in series to form an aspiring high-voltage work platform.
5. The production process is different. The thinner the polymer battery, the better the production, and the thicker the lithium battery, the better the production. This allows the application of lithium batteries to expand more fields.
6. Capacity. The capacity of polymer batteries has not been effectively improved. Compared with the standard capacity lithium batteries, there is still a reduction.
