Abstract

The invention aims to provide a battery shell manufacturing method, a battery shell and a battery. The battery shell manufacturing method comprises: S1, coating a layer of ink pattern on a metal plate, and coating solder on a non-graphite pattern area; S2, stacking at least one layer of metal plate on the metal plate, and performing hot rolling to form a composite plate; S3, filling high-pressure fluid along a non-compounded part of the graphite pattern to expand the pipeline, filling a heat transfer working medium into part of the pipeline, and sealing the pipeline; S4, performing bending to form a U shape, adding a bottom plate, and conducting fixed connection to form a metal piece with a cavity; and S5, installing end plates at the two ends of the metal piece. According to the battery shell manufacturing method, the soaking capacity and the heat dissipation capacity of the battery shell are greatly improved, the heat dissipation path is short, the heat dissipation efficiency is improved, the heat dissipation cost is reduced, and the requirement for efficient heat control of the electric core level is met.

Description

technical field [0001] The invention belongs to the field of lithium batteries, and in particular relates to a method for manufacturing a battery casing, a battery casing and a battery. Background technique [0002] In my country, the new energy industry has developed rapidly with the encouragement of national policies, and secondary batteries such as lithium-ion batteries have been widely used. Generally, the square battery uses a light and thin aluminum shell as the outer shell, plus the battery cell and electrolyte, and welds the upper cover plate to form a sealed shape. However, this square battery cannot effectively solve the problem of heat generation, which may lead to shortened battery life, or lead to smoke, fire or even explosion of the battery. In addition, traditional prismatic batteries need to use other auxiliary materials or devices outside the battery to help dissipate heat. The heat dissipation path is long, the heat dissipation efficiency is reduced, and t...
