NONAQUEOUS SECONDARY BATTERY AND A METHOD OF MANUFACTURING A NEGATIVE ELECTRODE ACTIVE MATERIAL

摘要

A non-aqueous secondary battery comprising a negative electrode, a positive electrode in which a chalcogenated substance containing lithium is used as a positive electrode active material and a non-aqueous ion conductor. The negative electrode contains a negative electrode active material which is a carbon material in which an amorphous carbon is adhered on the surface of graphite particles which are subjected to an oxidizing treatment.
