Title: SYSTEM AND METHOD FOR CHARGE PROTECTION OF A LITHIUM-ION BATTERY
Abstract:
A method for controlling a charge process of a solid-state battery having a sulfur-based positive electrode is provided. The method includes monitoring and storing a temperature of the solid-state battery and a predetermined interval, when the temperature exceeds a threshold temperature, monitoring the temperature of the solid-state battery and/or processing the stored temperature data of the solid-state battery, for an indication of sulfur sublimation, and terminating a flow of charge current upon detection of the indication of sulfur sublimation.
