Stoichiometric spinel LiMn{sub 2}O{sub 4} delivers a large initial capacity of 140 mA hr/g and has unstable rechargeability. The capacity fading of the cell on cycling occurs in the higher charge voltage range of x<0.45 in Li{sub x}Mn{sub 2}O{sub 4}. Nonstoichiometric spinel Li{sub 1+x}Mn{sub 2}O{sub 4} has a slightly lower capacity of 110 mA hr/g and has an excellent cycling behavior.
