Abstract
The multicomponent hydrogen storage alloy with composition MMNi3.31Mn0.37A10.28Co0.64 was used as a negative electrode material. After packing the alloy particles in a porous nickel substrate, press forming was carried out to bond them. The effects of particle size and forming pressure on electrode performance were examined in 6 m KOH solution. The electrochemical properties of the negative electrode, such as discharge capacity and high-rate dischargeability, were remarkably improved by increasing the alloy particle size and forming pressure.
