Abstract
A gel-type storage battery is made by preparing porous electrolyte pads having internal pockets containing a dry powdered gelling agent, and inserting the pad between adjacent battery electrodes before addition of acid. The gelling agent may include acid resistant superabsorbing polymer particles, which cause the pads to swell into intimate contact with the electrodes upon addition of the aqueous acid.
