Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
1 . A method for controlling a charge process of a solid-state battery having a sulfur-based positive electrode, the method comprising: 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. 2 . The method according to claim 1 , wherein the monitoring is performed by a temperature sensor. 3 . The method according to claim 1 , wherein the monitoring for sulfur sublimation comprises monitoring the temperature of the solid-state battery for a drop in temperature that occurs at a rate greater than a predetermined threshold rate. 4 . A battery charger for a solid state battery having a sulfur-based positive electrode, the battery charger comprising: a current providing section configured to provide current to the solid-state battery; a monitoring section configured to monitor and record a temperature of the solid-state battery; and a controller configured to: when the temperature of the solid-state battery exceeds a threshold temperature, monitor the temperature of the solid-state battery and/or process the stored temperature data of the solid-state battery, for an indication of sulfur sublimation; and to terminate a flow of current to the solid-state battery when an indication of sulfur sublimation is identified. 5 . Use of a battery charger according to claim 4 , for charging a solid-state battery comprising a sulfur-based positive electrode and a temperature sensor. 6 . The method according to the claim 2 , wherein the monitoring for sulfur sublimation comprises monitoring the temperature of the solid-state battery for a drop in temperature that occurs at a rate greater than a predetermined threshold rate.
