Title:
非水系二次電池負極用活物質並びにそれを用いた負極及び非水系二次電池
Document Type and Number:
Japanese Patent JP6960717
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an active material for a negative electrode of a nonaqueous secondary battery superior in charge and discharge cycle characteristics while suppressing the rise in resistance accompanying gas generation and in-battery coating formation owing to the decomposition of a nonaqueous electrolyte.SOLUTION: An active material for a negative electrode of a nonaqueous secondary battery comprises: an active material (A) allowing lithium ions to go thereinto and out thereof; and a compound (B) and/or a polymer of the compound (B). The compound (B) has a radical polymerizable unsaturated bond in a molecular structure, and it is at least one organic acid derivative selected from a group consisting of an organic acid anhydride, an organic acid ester and an organic acid amide.SELECTED DRAWING: None
