PROBLEM TO BE SOLVED: To provide a lithium ion secondary battery having a high capacity and excellent cycle characteristics, and a vehicle equipped with the battery.SOLUTION: The lithium ion secondary battery includes a positive electrode and a negative electrode. The positive electrode contains a positive electrode active material containing no Li. The negative electrode contains a negative electrode active material containing a Li-inactive metal that will not form an intermetallic compound with Li, or a silicide of the Li-inactive metal, and elemental Si. At least one of the positive and negative electrodes contains a binder, and the binder is obtained by curing an alkoxysilyl-containing resin represented by the formula (I), where Rrepresents a C1-C8 alkyl group, Rrepresents a C1-C8 alkyl or alkoxy group, and q represents an integer from 1 to 100. |
