ACTIVE MATERIAL FOR NONAQUEOUS ELECTROLYTE BATTERY AND NONAQUEOUS ELECTROLYTE BATTERY HAVING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a high performance nonaqueous electrolyte battery using lithium titanate as an active material.

SOLUTION: This invention uses the active material for the nonaqueous electrolyte battery having carbon in at least a part of a surface and including a lithium titanate particle on which a value of the atomic ratio (C/Ti) of the carbon to titanium determined by an X-ray photoelectric spectroscopic analysis is 6 or more. 6.3≤(C/Ti)≤8 is further desirable. Ethanol is desirably used as a carbon source.
