METHOD OF ESTIMATING OR PREDICTING DETERIORATED STATE OF SULFIDE-BASED SOLID BATTERY

摘要

PROBLEM TO BE SOLVED: To provide a method of estimating or predicting a deteriorated state of a sulfide-based solid battery applied to usages under a changeable use environment caused by moisture.SOLUTION: The method of estimating or predicting a deteriorated state of a sulfide-based solid battery includes: calculating a moisture content permeated into a sulfide-based solid battery on the basis of temperature and relative humidity of the sulfide-based solid battery; and estimating or predicting a deteriorated state of the battery on the basis of the calculated moisture content.
