Expansion tape

Expansion tape is composed of OPS substrate or modified TPU substrate, coated with anti electrolyte pressure-sensitive adhesive. Developed and manufactured swelling/expansion tape for lithium battery drum testing. Used for fixing the end of high magnification batteries, replacing traditional termination tape. The principle is to generate volume expansion under the action of electrolyte, fill the gap between the battery cell and the shell, reduce the shaking of the battery in vibration environment, and prevent short circuits.
