SPINEL-TYPE LITHIUM MANGANESE TRANSITION METAL OXIDE

摘要

Provided is a new spinel type lithium manganese transition metal oxide for use in lithium batteries, which can increase the capacity retention ratio during cycling, and can increase the power output retention ratio during cycling. Disclosed is a spinel type lithium manganese transition metal oxide having an angle of repose of 50° to 75°, and having an amount of moisture (25° C. to 300° C.) measured by the Karl Fischer method of more than 0 ppm and less than 400 ppm.
