Explosion-resistant large capacitive lithium ion secondary battery |
摘要 |
An active material free part of a positive electrode is coated with an over-coat material, wherein the over-coat material has at least one of the following properties: suppression of heat transfer from the second part of the electrode to the separator; reduction of a heat transfer rate from the second part of the electrode to the separator; prevention of transfer of excess heat from the second part of the electrode to the separator; electrical isolation of the second part of the electrode from the separator; prevention of charges generated in the first active material from becoming concentrated in the second part of the electrode and discharged from the second part; and prevention of the separator from being melted by a current discharge from or into the second part of the electrode through the separator until the current discharge is shut down by a fuse function of the separator.
