| 摘要 |
The present invention pertains to a negative electrode for a lithium rechargeable battery, containing an acid anhydride represented by general formula (1), and provides a rechargeable battery having outstanding cycle characteristics and storage characteristics under high temperatures. (In the formula, X1, X2 and X respectively represent independent C1-50 hydrocarbon groups or single bonds, R1and R2 respectively represent C1-6 hydrocarbon groups or hydrogen, m1 and m2 respectively and independently represent 1 or 2, n1, n2 and n respectively and independently represent 0 or 1, where if n represents 1, X1 may form a ring structure together with R1, X2 may form a ring structure together with R2, but if n represents 0, X1, X2, R1 and R2 may both form ring structures as a whole.) |
