<p>A cathode composition for a lithium ion battery that contains lithium having the formula (a) Liy[M1(1-b)Mnb]O2 or (b) Liy[M1(1-b)Mnb]O1.5+C where 0≤y<1, 0<b<1 and 0<c<0.5 and M1 represents one or more metal elements, with the proviso that for (a) M1 is a metal element other than chromium. The composition is in a 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 30C and a final capacity of 130 mAh/g using a discharge current of 30 mA/g.</p> |
