Abstract
A bipolar electrode for a Pb-acid battery comprising a lead septum plate and a porous coating on at least one face of the septum plate for anchoring at least the positive active material paste to the septum. The porous coating comprises multiple layers of lead particles fused together and to the septum face so as to define a plurality of interconnected, interstitial pores therebetween. The particles are fused droplets of lead arc-sprayed into the surface of the septum. A particular bipolar and battery construction useful with the bipolar electrode is disclosed.
