Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of chemical formation and batching, and particularly relates to a chemical formation negative pressure mechanism compatible with multiple channels. BACKGROUND

[0002] After the production of lithium batteries is completed, the lithium batteries need to be subjected to chemical formation and batching. Chemical formation is to perform initial charging and discharging on the lithium batteries to activate the internal chemical substances, and only after the chemical formation is completed, the lithium batteries can start normal charging and discharging. Batching is to sort the capacity of the lithium batteries. During the chemical formation of the lithium batteries, waste gas is generated inside, and residual electrolyte flows out, which will affect the production of the lithium batteries, so that the performance of the lithium batteries cannot meet the requirements. Therefore, a negative pressure mechanism is needed to collect the generated waste gas and residual electrolyte.

[0003] However, the conventional negative pressure mechanism is single-channel (fixed channel number), and can only be used for single-channel chemical formation equipment. If the negative pressure mechanism is to be used in combination with chemical formation equipment of different channels, manual disassembly and transformation of the negative pressure mechanism are needed, which is low in efficiency and prone to errors during the disassembly and transformation process.

[0004] Therefore, how to provide a chemical formation negative pressure mechanism compatible with multiple channels to improve the compatibility of the chemical formation negative pressure mechanism has become a technical problem to be solved. SUMMARY

[0005] The present application solves the technical problem of providing a chemical formation negative pressure mechanism compatible with multiple channels to improve the compatibility of the chemical formation negative pressure mechanism.
