Description

Technical Field

[0001] This utility model relates to the field of battery processing technology, and in particular to an automatic liquid injection device for needle batteries. Background Technology

[0002] Battery electrolyte is the carrier of ion transport in a battery, ensuring sufficient lithium ions to travel between the positive and negative electrodes during charging and discharging, thus achieving reversible cycling. Therefore, the amount of electrolyte injected and the degree of electrolyte absorption by the positive and negative electrodes are key factors affecting battery performance. Traditional needle-type battery electrolyte filling equipment often cannot automatically load and unload batteries, requiring manual operation. Prolonged contact with this process can harm the health of workers and easily lead to electrolyte contamination, affecting product quality. This paper proposes an automated electrolyte filling device that avoids human contamination during operation and improves product quality. Utility Model Content
