Sealed lead-acid battery
First Claim
1. A sealed lead-acid battery of the gas recombination type comprising:
- positive and negative plates and separators therebetween;
an immobilized electrolyte substantially completely retained within said plates and separators;
a container holding said positive and negative plates and said electrolyte; and
means for supplying a lower part of said positive and negative plates with water formed by reaction of phase change of substances within said container, said means providing a greater amount of water to the lower part of the positive and negative plates than to upper parts of the plates.

Abstract
A sealed lead-acid battery of the absorption-at-the-negative-electrode type employing an immobilized liquid electrolyte in which stratification of the electrolyte is eliminated. In accordance with the invention, a lower part of the positive and negative plates is supplied with water formed by a reaction or phase change of substances contained within the container of the battery. In a preferred embodiment, this is done by producing a temperature difference within the container. Also, water may be provided to the lower part of the positive and negative plates by increasing the speed of certain reactions at the lower part of the negative plate relative to the upper part thereof.
