COMPOSITE POSITIVE ACTIVE MATERIAL FOR LITHIUM-ION BATTERY

摘要

Lithium-nickel-manganese-cobalt-aluminum-oxide compounds (I) are new. Lithium-nickel-manganese-cobalt-aluminum-oxide compounds of formula (Li 1+x(Ni aMn bCo cAl y) 1-xO 2) (I) are new, where the atomic quantity of manganese is 95-100% of the atomic quantity of nickel. a+b+c+y : 1; (1+x)/(1-x) : 1.05-1.25; and y(1-x) : >= 0.015.
