The lithium battery cell contains components such as separators, positive/negative electrode plates, and electrode ears. These components are immersed in the electrolyte and require tape to maintain stable adhesion to each component throughout the entire life cycle of the lithium battery. Our battery tape can maintain high adhesion, zero precipitation, metal free, non discoloration of the electrolyte, and non discoloration of the tape in a fully immersed electrolyte environment for a long time. Widely used in various types of lithium batteries.
