リチウムイオン二次電池用負極炭素材料、及びその製造方法

Japanese Patent JP4724390

B2

To provide a manufacturing method of a negative electrode carbon material for a lithium-ion secondary battery in which the negative electrode carbon material for the lithium-ion secondary battery which is as good as conventional ones can be manufactured more inexpensively by utilizing effectively Chujiro bran or Jojiro bran (mixture of aleurone layer and a part of endosperm) of rice.

This is the negative electrode carbon material for the lithium-ion secondary battery in which a rice starch part in which pericarp and testa are removed from brown rice is calcined. The rice starch part is preferably the Chujiro bran or Jojiro bran in polishing the brown rice, and a powder X-ray (CuKα) diffractive figure of the negative electrode carbon material for the lithium-ion secondary battery has preferably a relatively broad peak in 2θ=40-50° and a sharper peak in 2θ=42-44°.
