Processo para produzir lI2 MBMM2-B 04 e óxido de metal de multicomponentes com lítio catódio para uso em célula eletroquímica secundária de íon de lítio e célula eletroquímica secundária de íon de lítio

摘要

A method for manufacturing Li2MbMn2-bO4, in which M represents a metal other than manganese, and b is from 0 to 1.999, which comprises contacting LiMbMn2-bO4 with a lithium salt in a liquid medium to'form a mixture; and adding a reducing agent to the mixture, heating for sufficient time to effect substantially complete conversion, and separating the product Li2MbMn2-bO4 thus obtained.
