ELECTRODE FOR NON-AQUEOUS ELECTROLYTE POWER STORAGE DEVICE, NON-AQUEOUS ELECTROLYTE POWER STORAGE DEVICE, AND METHOD FOR PRODUCING SAME

Provided is a non-aqueous electrolyte power storage device that traps hydrogen sulfide gas generated from the inside of a power storage device for some reason in the power storage device and prevents outflow of the hydrogen sulfide gas to the outside of the power storage device. A non-aqueous electrolyte power storage device in which a coating material having a silanol group is present at least on a surface of an electrode active material layer and a sulfur-based material is contained in a cell, the electrode active material layer contains an electrode active material and a resin-based binder, the electrode active material is an active material capable of being alloyed with a metal element identical to an ion species responsible for electrical conduction or an active material capable of absorbing ions responsible for electrical conduction, and the coating material having a silanol group is a silicate containing a siloxane bond as a component or a silica fine particle aggregate (containing a siloxane bond as a component).
