MANUFACTURE OF NEGATIVE ELECTRODE FOR NON-AQUEOUS ELECTROLYTE SECONDARY BATTERY

摘要

PROBLEM TO BE SOLVED: To provide a negative electrode for a non-aqueous electrolyte secondary battery which high entering dencity and excellent cycle property and is free of dendrites by eliminating capacity decrease due to the difference between a charging capacity and a discharging capacity in the first time charging and dischaging. SOLUTION: The negative electrode manufacturing method of the present invention involves a process to heat a carbon material in reduced pressure or a process to heat a carbon material together with a lithium compound in an inert atmosphere. The method also involves a process to carbonize the carbonizable material by adding a lithium compound to a solid-phase carbonizable material or a liquid-phase carbonizable material and carrying out heating treatment in an inert atmosphere.
