1. Different raw materials
Lithium batteries generally refer to aluminum shell batteries, the electrolyte is liquid, and the outer packaging material is aluminum shell. Polymer lithium battery refers to an all-solid or gel lithium-ion battery with electrolyte. Aluminum-plastic composite film is generally used as packaging material.
2. Different structures
Polymer lithium batteries can be made thin, in any area, and in any shape because the electrolyte can be solid or colloidal rather than liquid; lithium battery packs use electrolytes and require a strong shell as secondary packaging. Electrolyte. Therefore, this also adds some weight to the lithium battery.
3. Different security
When polymer lithium batteries are mostly soft-packed lithium batteries, aluminum-plastic film is used as the outer casing. When organic electrolytes are used inside, even if the liquid is very hot, it will not explode because the aluminum-plastic film polymer battery is solid or colloidal and has no leakage. , just breaks naturally. However, lithium batteries have a certain risk of explosion and fire.
