Electrode for non-aqueous electrolyte electrical storage device, non-aqueous electrolyte electrical storage device, and manufacturing method thereof

摘要

(assignment) A non-aqueous electrolyte power storage device is provided that traps hydrogen sulfide gas generated from inside the power storage device for some reason in the power storage device, thereby preventing the hydrogen sulfide gas from flowing out to the outside of the power storage device. (Solution) A non-aqueous electrolyte power storage device in which a coating material having a silanol group is present at least on the surface of an electrode active material layer and includes a sulfur-based material in a cell, wherein the electrode active material layer includes an electrode active material and a resin-based binder, and the electrode active material conducts electricity An active material capable of alloying with the same metal element as the ionic species in charge or an active material capable of occluding ions responsible for electrical conduction, and a coating material having a silanol group is a silicate containing a siloxane bond in its component or (including a siloxane bond in the component). and) a non-aqueous electrolyte power storage device that is an aggregate of silica fine particles.
