Analysis of gases generated from all solid-state Li-ion batteries using sulfide-based solid electrolytes
MSTips No. 351
Understanding the gases generated inside a rechargeable battery when it is in use is considered in terms of performance maintenance and quality control. By using an experimental battery from which internally generated gases can be extracted, it is possible to identify the gas species generated and estimate changes in the amount of gas generated, although this is different from the actual operating environment of the battery, which is an enclosed space. In this paper, we focus on the gases generated during the charging and discharging of all-solid-state batteries and present an example of analysis using a mass spectrometer.
