Introduction: Lithium batteries are classified according to their packaging methods, which can be mainly divided into three categories, namely: square, cylindrical and soft packaging. The main difference between the three types of batteries is that the square cylindrical battery uses metal material as the external shell of the battery, and the flexible packaging battery uses aluminum plastic film flexible material as the external shell of the battery. The three types of batteries differ in shape, and the manufacturing process of winding and lamination is also adopted.
