Abstract
Provided are compositions useful as cathodes for lithium-ion batteries. The compositions include lithium mixed metal oxides of the formula, Li[LixNiyMnz]O2, whereinx+y+z=1, 0<x<0.20, 0.28≦y≦0.75, and 0.25≦z≦0.49, said composition characterized as being in the form of a single phase. Also provided are electrodes that include the provided compositions as well as battery packs and electronic devices that include the provided electrodes.
