Cathode tab tape
Cathode tab tape: a special adhesive tape used specifically for the cathode tab of cylindrical lithium batteries, with high strength, high temperature resistance, electrolyte corrosion resistance, and shear resistance. It is used to reinforce, protect, and insulate the cathode tab. It wraps around the welding points of ultrasonic welding to prevent the welding points from piercing the diaphragm and causing short circuits in the core;
High temperature resistance and electrolyte corrosion resistance; Prevent the internal resistance of the battery from increasing. "
