higher reduction potential. They exchange one electron during electrochemical reaction and have a higher proton diffusion coefficient. The mechanism of the electrode reaction is proton diffusion, and the proton diffusion coefficient is 5.67?10-10 cm2/s. Moreover, they reveal a higher discharge capacity than b-Ni(OH)2/b-NiOOH because they exchange one electron per nickel atom during charge......
