BIPOLER STOMME FOR ELEKTROD TILL EN BLYACKUMULATOR

摘要

A bipolar electrode support structure for use in a lead acid battery is constituted by a porous matrix of valve metal, impregnated with lead or a lead alloy, and is provided on at least one surface thereof with a rim-portion at which little or no lead is exposed. The rim-portion is used to maintain an electrolyte-tight seal in operation.
