A novel cureless pure lead oxide plate for valve-regulated lead-acid batteries

Abstract

Pure lead oxide has been tested as a starting material for VRLA lead-acid batteries. The influence of the acidto-oxide ratio and the paste density on the plate formation and battery performance has been investigated. The results show that the plates can be directly formed without undergoing the conventional plate curing process if pure lead oxide is used. The new process shows significant advantages in simplifying the conventional plate making processes for lead acid batteries and reducing the production cost and time.
