Bipolar battery electrode and method.

摘要

A bi-polar electrode for a Pb-acid battery comprises a lead septum plate (2) and a porous coating (16) on at least one face (18) of the septum plate (2) for anchoring at least a positive active material paste (24) to the septum plate (2). The porous coating (16) comprises multiple layers of lead particles (20) fused together and to the septum face (18) so as to define a plurality of interconnected, interstitial pores (22) therebetween. The particles (20) are fused droplets of lead arc-sprayed into the surface of the septum plate (2). A particular bi-polar battery construction useful with the bi-polar electrode is also disclosed.
