Abstract
Abstract A primary battery comprising aluminum and silver oxide utilizes a pre-hea potassium hydroxide electrolyte for the generation of power. The battery with its electrolyte preheated to a minimum of 120° F is capable of providing a very high electrical energy source of minimum weight and volume for underwater propulsion systems. The electrolyte may be brought up to temperature by either conventional heating apparatus or a unique mixing procedure for providing an instantaneous temperature use.
