Abstract
To provide an electrode for non-aqueous electrolyte batteries, which traps hydrogen sulfide gas, generated from the inside thereof for some reason, in the electrode, and suppresses the outflow of hydrogen sulfide gas to the outside of the battery. An electrode for lithium ion batteries includes a coating material which contains a silanol group and is present on at least a surface of an active material layer. The active material layer contains a sulfur-based material and a resin-based binder. The sulfur-based material is an active material capable of alloying with lithium metal or an active material capable of occluding lithium ions. The coating material containing the silanol group is a silicate having a siloxane bond or a silica fine particle aggregate having a siloxane bond as a component.
