摘要：
A cathode composition for a lithium-ion battery having the formula Li[M1(1-x)191Mnx191]O2191 where 0 x 1 and M1 represents one or more metal elements, with the proviso that M1 is a metal element other than chromium. The composition is in the form of a single phase having an O3 crystal structure that does not undergo a phase transformation to a spinel crystal structure when incorporated in a lithium-ion battery and cycled for 100 full charge-discharge cycles at 30° C and a final capacity of 130 mAh/g using a discharge current of 30 mA/g.
