Analysis of the difference between lithium battery and polymer battery

Lithium polymer battery is an upgraded product of lithium battery. Relative to the current popular lithium battery, it has the advantages of large capacity, small size, safety and so on. However, due to the time required for the replacement of the entire industry chain, its cost is currently relatively high, and it is only used in high-end digital products. Lithium polymer battery refers to a lithium battery in which all solid state or gel is too electrolyte. Generally, aluminum-plastic composite film is used as packaging material. 1. Different raw materials The raw materials of lithium batteries are electrolytes (liquid or gel); the raw materials of polymer lithium batteries are electrolytes including polymer electrolytes (solid or gel) and organic electrolytes. Second, the safety aspect is different. Lithium batteries are easy to explode in high temperature and high pressure environments; polymer lithium batteries use aluminum plastic film as the outer shell, and when organic electrolytes are used inside, they will not explode even if the liquid is very hot. 3. Different shapes of polymer lithium batteries can be thinner, arbitrarily shaped, and arbitrarily shaped, because the electrolyte can be solid or colloidal rather than liquid. Lithium batteries use electrolyte and require a solid shell as a The secondary package contains the electrolyte. Fourth, the battery cell voltage is different. Because the polymer battery uses polymer materials, it can be made into a multi-layer combination in the battery cell to achieve high voltage, while the nominal capacity of the lithium battery cell is 3.6V, if you want to achieve high voltage in actual use , You need to connect multiple cells in series to form an ideal high-voltage working platform.
