摘要:
The invention relates to a LiaNixCoyMzO2±eAf composite oxide for use as a cathode material in a rechargeable battery, with a non-homogenous Ni/Al ratio in the particles, allowing excellent power and safety properties when used as positive electrode material in Li battery. More particularly, in the formula 0.9
