Abstract
A storage battery having various cell constructions to increase the surface-to-weight ratio of active material exposed to electrolyte ions, to reduce internal resistance, and to extend the life of the battery is provided. One configuration for the battery cell utilizes pleated positive and negative plates which are monolithically coupled to respective electrodes. Another configuration for the battery cell utilizes a single positive plate and a single negative plate which are interrelated in, for example, a serpentine configuration.
