BATTERY AND MANUFACTURING METHOD THEREOF

摘要

A battery and a manufacturing method thereof are provided. The battery includes a shell and a battery cell which is sealed in the shell and has a positive outlet terminal and a negative outlet terminal, the shell includes a rigid substrate and a soft composite plate, the substrate connects with the composite plate to form a sealed cavity for holding the battery cell, the battery cell is provided in the cavity, and the substrate generally is a metal plate. The metal substrate, as a part of the shell, not only has a high anti-explosion safety performance of the flexible packaging cell, but also improves the mechanical strength of the shell, and the safety of the battery in the use and manufacturing process is improved because the battery shell is not easily punctured; also the production cost of the battery is reduced because the production cost of the metal plate is low relative to the composite plate.
