Is lithium battery better or polymer battery better?

You mean the full name of polymer battery is polymer lithium battery. It is a kind of lithium battery. In terms of batteries, lithium batteries are divided into first-generation steel-shell lithium batteries, second-generation aluminum-shell lithium batteries, and third-generation polymer lithium batteries. Since the polymer battery is encapsulated with an aluminum composite film, the film is only 0.3m thick, and the space for the internal reaction material is the largest. The aluminum composite film is much lighter than the steel shell and aluminum shell. The aluminum composite film can be pulled up, which effectively slows down The pressure generated when the battery reacts badly to avoid the possibility of explosion. The polymer lithium battery is the battery with the highest capacity, the lightest weight and the best safety among the lithium batteries.
