Lithium metal oxide

摘要

Provided is a novel lithium metal complex oxide powder, which is capable of maintaining stability of the slurry viscosity during storage of a slurry even when D50 thereof is less than 10 μm, and which is also capable of suppressing a decrease in the discharge capacity during high temperature cycles. Proposed is a lithium metal complex oxide which is characterized by having a D50 of less than 10 μm and a carbon amount per unit BET specific surface area of from 1100 ppm/(m2/g) to 7500 ppm/(m2/g).
