A process is described for the manufacture of negative accumulator electrodes having a current conducting carrier skeleton and an active material for the reversible electrochemical storage and restitution of hydrogen on charging and discharging. The powder particles of the active material are at least partially enveloped and coated with a hydrogen-permeable copper layer and the copper-coated active material particles are processed by heating to sintering temperatures with simultaneous application of pressure to form a porous, mechanically-stable electrode permeated with a sintered copper carrier skeleton of sintered copper coated on the active material particles. |
