ABSTRACT:
A battery plate separator is characterized by polypropylene filter media material which is readily formed into pouches for receiving and encapsulating battery plates. The separator enables a free flow of electrolyte ions between adjacent plates while simultaneously preventing electrode dendrite penetration therebetween, is highly resistant to deterioration in the presence of electrolytes normally encountered in batteries, significantly extends the life of batteries constructed therewith, and provides a very thin yet highly efficient wrapping around the plates so that a greater number of plates may be packaged into a battery of given size for increased battery capacity.
