Description

technical field

[0001] The invention relates to the technical field of lithium battery production, in particular to an electrolyte injection device for lithium ion batteries. Background technique

[0002] Electrolyte is the medium used in chemical batteries, electrolytic capacitors, etc., providing ions for their normal operation. Electrolyte is an essential part of chemical batteries, so a suitable electrolyte injection device is also essential.

[0003] At present, most of the battery electrolyte injection methods on the market use the method of assembly line operation, and often need manual assistance to move the battery from the conveying line to the liquid injection station, and the liquid injection can only be performed after the corresponding positioning tool is placed. After the liquid is filled, the battery is moved back from the filling station to the conveying line. This process is seriously time-consuming and labor-intensive, which restricts the production effi...
