Auxiliary tool for assembling lithium ion button cell in laboratory

Technical Field

The utility model relates to a laboratory lithium ion button cell installation field is an appurtenance of laboratory lithium ion button cell equipment.

Background

Lithium ion button cells are common batteries in new energy laboratories, and their performance is often affected during the assembly process. In the process of assembling the conventional button cell, the positive and negative electrodes, the steel sheets and the spring pieces are easy to deflect, which can increase the probability of short circuit of the cell, thereby affecting the performance of the cell. The short-circuited battery is not normally used and thus needs to be disposed of. From the perspective of laboratory sustainability, not only would short-circuited batteries increase experimental costs, but scrapped lithium ion batteries also pollute the environment. The appurtenance of button cell equipment that this patent designed can effectively reduce the probability that the short circuit took place for the battery at the battery equipment in-process, is favorable to reducing laboratory cost and environmental pollution.
