technical field

The utility model relates to the technical field of lithium battery production equipment, in particular to a pole cutting earphone for lithium battery production.

Background technique

Lithium battery refers to a battery containing lithium (including metal lithium, lithium alloys, lithium ions, and lithium polymers) in an electrochemical system. Lithium batteries can be roughly divided into two categories: lithium metal batteries and lithium ion batteries. A lithium battery is a rechargeable battery that mainly relies on the movement of lithium ions between the positive and negative electrodes to work. During the charging and discharging process, lithium ions are intercalated and deintercalated back and forth between the two electrodes: when the battery is charged, lithium ions are deintercalated from the positive electrode, inserted into the negative electrode through the electrolyte, and the negative electrode is in a lithium-rich state; during discharge, the opposite is true.

In the production process of lithium batteries, the exposed tabs need to be cut to make the lengths of the positive and negative tabs suitable to meet the size requirements of PACK welding.
