| 摘要 |
The purpose of the present invention is to provide a lithium ion battery that can suppress internal short failure without impacting battery performance, and that can improve reliability. The present invention provides a lithium ion battery that is characterized by including the following: a positive electrode and a negative electrode; a separator for insulating the positive electrode and the negative electrode from each other; and an electrolytic solution in which a charging and discharging reaction is carried out between the positive electrode and the negative electrode; and 0.0001-0.001wt% of an internal short inhibitor for suppressing internal short failure in the electrolytic solution. |
