1. Different raw materials

　　One of the differences between polymer lithium batteries and ordinary batteries is that the raw materials used for their production are different. The raw materials for lithium-ion batteries are electrolyte (liquid or colloid), while the raw materials for polymer lithium batteries are electrolytes. There are polymer electrolytes (solid or colloidal) and organic electrolytes.

　　2. Differences in security

　　In terms of safety, it is also different from ordinary lithium batteries because lithium-ion batteries simply 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 internally, even if the liquid is very hot, it will not burst.

　　3. Different shaping

　　Polymer batteries can achieve thinness, spaciousness, and arbitrary shape because their electrolytes can be solid and gelatinous instead of liquid. Lithium batteries use electrolytes and require a sturdy outer shell as a secondary packaging to contain the electrolyte.

　　4. The voltage of the battery cell is different

　　Because polymer batteries use polymer materials that can be combined into multiple layers within the cell to achieve high voltage, while lithium battery cells have a nominal capacity of 3.6V. To achieve high voltage in practical applications, multiple cells need to be connected in series to form a fully loaded high voltage operating platform.
