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.

To provide a negative electrode of a lithium ion battery excellent in cycle life characteristics. The negative electrode for a lithium ion battery includes an Si-based material as an active material, wherein a skeleton-forming agent including a silicate having a siloxane bond or a phosphate having an aluminophosphate bond as an ingredient is present on the surface and inside of an active material layer, and the skeleton of the active material is formed with the skeleton-forming agent.

A conventional bipolar battery is constituted of a combination of cells hermetically sealed for preventing a liquid junction and preventing corrosion of a peripheral device due to a liquid leakage. Therefore, electrolytic solution injecting processes are carried out as many as the number of cells, so that much times and costs have been required for manufacturing a large-scale battery. In addition, a wiring space has been required since the cells are connected to one another with wires. The use of a current collector formed of a one-end closed tubular conductor, the current collector having a bottom protruding outward to form a protrusion, eliminates the wiring space and achieves a reduction in ohmic loss due to the wires. In addition, an electrolytic solution in one cell is separated by a water-repellent sheet from an electrolytic solution in another cell, so that a liquid junction is prevented.
