Technical Field

The invention relates to a lithium ion battery, in particular to a lithium ion aluminum shell battery and an assembly process.

Background

The lithium ion aluminum shell battery can be disassembled on an electric appliance, so that the application range is wide, but the traditional production of assembling the upper end head of the lithium ion aluminum shell battery adopts low-pressure injection molding, namely after the battery is assembled, the head is bonded with the upper end of the battery core into a whole by using the process of filling the head with injection molding hot melt adhesive. This process has the following drawbacks: due to the influence of expansion caused by heat and contraction caused by cold of the hot melt adhesive, the length and thickness of the battery are easy to exceed standards and are unstable and difficult to control; the head part of the battery is easy to collapse, incline and overflow during the injection molding process; the glue injection port is easy to form a mantle, the mantle needs to be manually processed, and the production cost is high; the hot melt adhesive injection molding process is difficult to realize automation and low in production efficiency.
