Lithium polymer battery

摘要

A lithium (Li) polymer battery is provided. The Li polymer battery includes: a positive plate (21) including a positive collector (21a) having a plurality of openings and a positive active material layer (21b) formed on at least one surface of the positive collector (21a); a negative plate (22) including a negative collector (22a) in a foil form, and a negative active material layer (22b) formed on at least one surface of the negative collector (22a); and a separator (23) between the positive (21) and negative (22) plates, for insulating the positive (21) and negative (22) plates.
