Abstract

An electrolyte-immobilizing mat for a mat-immobilized-electrolyte battery comprising a plurality of randomly oriented resilient fibers resistant to and wettable by sulfuric acid electrolyte, wherein the mat is held in a stressed, precompressed state by a resin which is substantially insoluble in sulfuric acid but is sufficiently degradable therein under battery formation conditions to free the mat from its stressed state during formation and allow it to swell within battery cell element. Thermosetting resins and particularly melamine-formaldehyde are preferred. The invention is particularly useful with mats made from glass fibers.
