Effect of Cu powder as compacting material on the discharge characteristics of negative electrodes in Ni–MH batteries

Influence of electroless coatings of Cu, Ni–P and Co–P on MmNi3.25Al0.35Mn0.25Co0.66 alloy used as anodes in Ni–MH batteries

“…The needle like growth of copper during electroless deposition led to decrease in contact resistance. Therefore, it is suggested that the improved electrode characteristics are attributed to the copper layer deposited on the metal hydride alloy particles by the dissolution and precipitation (DP) process [29]. The initial electrochemical performance of metal hydride electrodes, which use copper and nickel electroless plated hydrogen storage alloy particles shows improved performance, but the cycle lives are the same as that of a bare metal hydride electrode.…”
