Cathode compositions for lithium-ion batteries |
摘要 |
A cathode composition for a lithium-ion battery having the formula Li[M<SUP>1</SUP><SUB>(1-x)</SUB>Mn<SUB>x</SUB>]O<SUB>2 </SUB>where 0<X<1 AND M<SUP>1 </SUP>represents one or more metal elements, with the proviso that M<SUP>1 </SUP>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.
