Non-aqueous electrolyte secondary battery charging method, electronic device, battery pack, and charging device |
摘要 |
The present invention aims to quickly charge a non-aqueous electrolyte secondary battery including a heat-resistant layer between a negative electrode and a positive electrode. A method according to the present invention for charging a non-aqueous electrolyte secondary battery including a heat-resistant layer between a negative electrode and a positive electrode is provided with a step of performing pulse charge on the secondary battery, a step of detecting a change amount of a cell voltage associated with a change in the concentration polarization of the non-aqueous electrolyte as a polarization voltage, and a step of terminating the pulse charge when the polarization voltage increases to or above a predetermined threshold value. According to the present invention, it is possible to quickly charge the non-aqueous electrolyte secondary battery including the heat-resistant layer between the negative electrode and the positive electrode at such a borderline level as not to cause overcharge. |
