1. The raw materials for lithium-ion batteries are different. The raw materials for lithium-ion batteries are electrolyte (liquid or colloid); The raw materials for polymer lithium batteries are electrolytes, including polymer electrolytes (solid or colloidal) and organic electrolytes.

　　2. In terms of safety, lithium-ion batteries can easily 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. Polymer batteries can achieve thinness, arbitrary surface area, and arbitrary shape due to the fact that their electrolytes can be solid or gelatinous rather than liquid, while lithium batteries use electrolytes and require a sturdy outer shell as a secondary packaging to contain the electrolyte.

　　4. The voltage of the battery cells is different because polymer batteries use polymer materials, which can be made into multiple layers within the cells to achieve high voltage. On the other hand, 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 high voltage operating platform with a negative load.

　　5. The production process is different, and the thinner the polymer battery, the better it is produced, while the thicker the lithium battery, the better it is produced. This allows lithium batteries to expand their applications in more fields.
