Provided are compositions useful as cathodes for lithium-ion batteries. The compositions include lithium mixed metal oxides of the formula, Li[Lix NiyMnz]O2, wherein x + 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. |
