About Our Divisions

Battery Materials Division

Excercising our rich expertise,
we stand behind Japan's battery industries

Delivering the nickel-metal hydride batteries that support the future of hybrid vehicles and the lithium-ion batteries which support the future of Japan's electronic devices.

Product list

Hydrogen-absorbing alloys (metal hydrides)

水素吸蔵合金

These are used in the nickel-metal hydride batteries available commercially. More affordable than lithium-ion batteries, nickel-metal hydride batteries are now being used for hybrid vehicles. This alloy is truly supporting the next generation of Japan.

Manufacturing process

Hydrogen-absorbing alloys, anode coils

水素吸蔵合金、負極コイルの製造工程

Material production to support the latest advancements in industry and recycling to realize the effective application of resources.

Our battery materials division manufactures lithium cobalt oxide using cobalt oxide derived from our original wet process as the base material. In addition, we carry out recycling operations for the lithium-ion batteries which support the effective application of the world's limited resources.

Operations

Manufacture of lithium cobalt oxide

コバルト酸リチウムの製造

Used for the cathode active material found in lithium-ion batteries. Lithium-ion batteries are used in digital cameras, cellular phones, laptops, portable audio devices and more.
