OPZS, OPZV, and various industrial battery corrugated porous pads are mainly used as protective pads for pressure regulation in battery assembly to prevent deformation of the electrode plate and affect its lifespan. The porous shape increases ion exchange channels, therefore the pads become the commonly used products in battery production. The normal thickness of the corrugated porous pad is 2.5mm, the length and width can be adjusted according to customer requirements, and special specifications can also be customized separately.
