| titleOfInvention | Lithium ion secondary battery |
| abstract | By forming a porous insulating layer between the electrode and the separator, the porous insulating layer melts when the temperature of the battery rises and inhibits the transmission of lithium ions, thereby suppressing heat generation when the battery is internally short-circuited. . The lithium ion secondary battery of the present invention has a current collector, an electrode having a positive electrode or a negative electrode on at least one surface of the current collector, a separator for separating the positive electrode and the negative electrode, and a porous formed between the electrode and the separator. And a non-aqueous electrolyte. The porous insulating layer is made of a binder containing polyvinylidene fluoride (PVDF) and a melting point depressant, and the melting point depressant is a binder that is measured by a differential scanning calorimetry in the presence of a non-aqueous electrolyte. The melting start temperature and / or the melting peak temperature are reduced as compared with the case of only PVDF. |
