Negative electrode material for lithium ion secondary battery, negative electrode for lithium ion secondary battery and lithium ion secondary battery
Document Type and Number:
Japanese Patent JP6333529
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a negative electrode material for lithium ion secondary battery having an excellent initial coulomb efficiency even if silicon is used, and to provide a negative electrode for lithium ion secondary battery, and a lithium ion secondary battery including the negative electrode.SOLUTION: A negative electrode material for lithium ion secondary battery is produced by blending any one or both of silicon and silicon monoxide, a conductive assistant and a binder. A negative electrode for lithium ion secondary battery includes a negative electrode active material layer formed by using such a negative electrode material on a collector. A lithium ion secondary battery includes such a negative electrode.
