SULFIDE-CONTAINING SOLID ELECTROLYTE CELL, BATTERY PACK COMPRISING THE CELL, VEHICLE SYSTEM COMPRISING THE BATTERY PACK, AND METHOD FOR SENSING HYDROGEN SULFIDE

摘要

Disclosed is a sulfide-containing solid electrolyte cell wherein deterioration of the cell can be efficiently sensed. Also disclosed are a battery pack comprising the cell, a vehicle system comprising the battery pack, and a method for sensing hydrogen sulfide. Specifically disclosed is a sulfide-containing solid electrolyte cell which comprises: one or more electric power generating units each of which is provided with at least a positive electrode, a negative electrode and an electrolyte interposed between the positive electrode and the negative electrode; and a case housing the electric power generating units. The sulfide-containing solid electrolyte cell is characterized in that at least one of the positive electrode, the negative electrode or the electrolyte contains a sulfur-containing material, and at least one of a collector and a lead constituting a charge/discharge path or a lead connected to an accessory circuit attached to the charge/discharge path contains a material the electrical resistance of which is changed when the material is chemically reacted with hydrogen sulfide.
