Abstract
There is disclosed a lead acid battery and battery separator, the separator comprising a porous ceramic body manufactured from ceramic fibers welded together at their respective contact points such that the resulting separator body is substantially rigid and non-compressible and wherein the separator has a porosity of at least about 90%. The electrodes of the battery may be comprised of a similar porous ceramic material impregnated, respectively, with Pb and PbO.sub.2. A lead-containing foil may be maintained in close contact with each of the electrodes as current collectors attached to the battery terminals.
