CHARGING METHOD FOR NON-AQUEOUS ELECTROLYTE SECONDARY BATTERY, CHARGING/DISCHARGING METHOD, AND CHARGING SYSTEM FOR NON-AQUEOUS ELECTROLYTE SECONDARY BATTERY - A simplified explanation of the abstract
This abstract first appeared for US patent application 18272945 titled 'CHARGING METHOD FOR NON-AQUEOUS ELECTROLYTE SECONDARY BATTERY, CHARGING/DISCHARGING METHOD, AND CHARGING SYSTEM FOR NON-AQUEOUS ELECTROLYTE SECONDARY BATTERY
Simplified Explanation
The abstract describes a charging method for a non-aqueous electrolyte secondary battery that involves switching the control temperature from high to low based on the ratio of the amount of change in capacity of the carbon material to the amount of change in battery capacity, compared to the ratio for the silicon compound.
- Positive and negative electrodes in the battery perform intercalation and deintercalation of lithium ions.
- The negative electrode contains a carbon material and a silicon compound as active materials.
- The switching step is triggered when the ratio of capacity change for the carbon material exceeds that of the silicon compound.
Potential Applications
- Electric vehicles
- Portable electronic devices
Problems Solved
- Improved battery performance
- Enhanced battery safety

Original Abstract Submitted
A charging method for a non-aqueous electrolyte secondary battery according to one aspect of the present disclosure comprises a switching step for switching the control temperature of a non-aqueous electrolyte secondary battery from high temperature to low temperature, wherein the non-aqueous electrolyte secondary battery includes a positive electrode and a negative electrode which reversibly perform intercalation and deintercalation of lithium ions, and the negative electrode contains, as a negative electrode active material, a carbon material and a silicon compound. The timing of the switching step is determined by detecting that dQ/dQ, that is, the ratio of the amount of change in a capacity Qof the carbon material to the amount of change in a battery capacity Q, becomes larger than dQ/dQ, that is, the ratio of the amount of change in a capacity Qof the silicon compound to the amount of change in the battery capacity Q.
