Abstract

Metal hydride-nickel cell is one of the best choices for hybrid electric vehicle for its high specific energy density, security, reliability and renewability. However, its poor capability under high temperature and low specific power restrict its applications. Our studies on the metal hydride-nickel cell with different loading densities show that Ni(OH)₂ with CoOOH has good oxidation and reduction properties and proton spread rate when the loading density is 0.617kg/m². The power density and energy density can be as high as 1250W/kg and 49.4 W·h/kg respectively when Ni(OH)₂ with CoOOH was used in high power battery with the nickel foam.
