Abstract

A composition for prolonging battery life by reducing water loss and the degradation of properties due to dendritic precipitation, is refreshingly added to a battery electrolyte. By the refreshment of the composition, battery cycle life is substantially increased while degradation of the internal battery components is substantially reduced.
