Problems solved by technology

[0004] Lithium battery tape needs to have high-quality and stable working properties due to the application environment, such as electrolyte resistance, moderate peeling force and unwinding force, high temperature resistance, aging resistance, and excellent tensile strength. Lithium batteries in current technology exist due to limitations. There is a risk of explosion, and the aging damage of lithium battery tape due to lack of high temperature resistance is also one of the risk factors
