Cathode compositions for lithium ion batteries

TLDR
In this article, a cathode composition for a lithium-ion battery having the formula Li[M 1 (1-x) Mn x ]O 2 where 0 <x<1 and M 1 represents one or more metal elements, with the proviso that M 1 is a metal element other than chromium is presented.
Abstract
A cathode composition for a lithium-ion battery having the formula Li[M 1 (1-x) Mn x ]O 2 where 0<x<1 and M 1 represents one or more metal elements, with the proviso that M 1 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.
