Abstract
Abstract A porous electrode support for alkaline accumulators consisting of a sintered mass of chemically nickel-coated graphite particles with a particle size of 5 to 200 Mu . A reinforcing fiber layer is sintered to the particles and can consist of synthetic resin or vitreous fibers coated with nickel. Preferably the fiber reinforcing mats or webs are provided on both faces of the flat support.
