Metal hydride materials are actively used as anode materials for Ni-MH batteries. Various high conductive additives (graphite, nickel, copper, etc.) to the active hydrogen storage material are used to increase the electrical conductivity and mechanical stability of the electrodes. In this work, metal hydride electrodes based on AB5 type alloy mixed with carbonyl nickel in various mass ratios are prepared and studied. The electrochemical properties of the prepared electrodes, such as activation performance, maximum discharge capacity, and high rate dischargeability are investigated in detail.
