INTRODUCTION
Fiberglass battery separator tissue is characterized by large area weight, low DC mass resistivity, high absorption capacity, good acid resistance, low content of deoxidized potassium permanganate (KMnO4) organic substance and impurity as well as proper stiffness, smooth surface, and uniform thickness. The compound lead acid battery separator made of this tissue has the advantages of low resistivity, high porosity and large capacity, better mechanical strength and vibration resistance. The battery fixed up with this type of separator plates possesses stronger starting power and longer lifetime so that it has become a trend to replace the traditional battery separator plate with this new compound plate made of fiberglass.
