Description

Replaceable plug type tray assembly

Technical Field

The utility model relates to a battery ization becomes the field, especially relates to a can replace plug-type tray subassembly.

Background

The lithium ion battery is usually formed just after being produced, that is, the battery is charged once to activate the battery, and the battery can start to be normally charged and discharged after the formation is completed. The formation of the battery is the initialization of the battery, so that the active substances of the battery are activated, and the process of energy conversion is carried out. And because the lithium ion battery is easy to generate gas in the formation process and the volume is expanded, and when the gas generation is more, the gas can enter between the pole piece and the diaphragm, the contact between the pole piece and the diaphragm is reduced, and the positive migration of lithium ions is hindered. Therefore, a clamp is usually required to pressurize the battery in the formation process of the lithium ion battery to inhibit gas from entering the pole piece or between the pole piece and the diaphragm, so that the adhesion between the pole piece and the diaphragm is increased, and the positive migration of lithium ions is facilitated. Further, by pressurizing the battery, the expansion of the battery negative electrode can be suppressed to some extent.
