Zisun's AGM battery separator is one of the core materials for valve-regulated lead-acid (VRLA) batteries. It possesses excellent insulation properties, chemical stability, and a rich microporous structure.

The separator is designed to wrap around the battery lead plates, preventing contact between the lead plates while absorbing the electrolyte and allowing the passage of electrons in sulfuric acid. This ensures the safety, reliability, service life, and capacity of valve-regulated lead-acid batteries.
