What are the differences between lithium battery pack and polymer lithium battery?

The difference between lithium battery pack and polymer lithium battery: The concept of lithium battery includes lithium battery and lithium polymer battery. If we compare the difference between lithium polymer battery and lithium battery pack in a broad and narrow sense, then the only thing is the relationship between the concept and the concept, and the lithium polymer battery is included in the lithium battery. Lithium battery pack generally refers to aluminum shell battery, the electrolyte is liquid, and the outer packaging material is aluminum shell. Lithium polymer battery refers to a lithium battery that is all solid or gel too electrolyte. Generally, aluminum-plastic composite film is used as packaging material. ①The raw material polymer lithium battery refers to the use of polymer materials in at least one of the three major components of the positive electrode, the negative electrode or the electrolyte. Macromolecules mean large molecular weights, and the corresponding concept is small molecules. Macromolecules have high strength, high toughness and high elasticity. The polymer materials currently developed for polymer batteries are mainly used for positive electrodes and electrolytes. ②The shape difference polymer lithium battery can be thinner, any area and any shape, because its electrolyte can be solid or colloidal rather than liquid; lithium battery packs use electrolyte and require a solid shell as The secondary package contains the electrolyte. Therefore, this also adds a part of the weight of the lithium battery. ③Safety Most of the current polymer batteries are soft-packed lithium batteries, which use aluminum plastic film as the outer shell. When organic electrolytes are used inside, they will not explode even if the liquid is hot, because the aluminum plastic film polymer batteries use solid or colloidal forms. The leaking liquid just ruptured naturally. Disclaimer: Some pictures and content of articles published on this site are from the Internet. If there is any infringement, please contact to delete.
