Material of nickel-metal-hydride batteries (spherical nickel hydroxide)
Our industry-leading/unique technology

We have the largest share in global market in manufacturing positive electrode materials for nickel-metal-hydride batteries.

We develop and manufacture positive electrode materials which are the key materials for rechargeable batteries such as nickel-metal-hydride batteries and lithium-ion batteries. Of special note is that we succeeded in developing the world’s fi rst technology of transforming the shape of nickel particles, which constitute the material of positive electrode for nickel-metalhydride batteries, into spherical shape. This new technology realized to increase fi ll ration of nickel hydroxide by reducing void space between particles when nickel hydroxide is packed into limited space. Thus, our new technology has contributed to higher battery capacities.

Description of our business

Manufacturing and sales of positive electrode materials for batteries etc.
▪Nickel hydroxide
▪Ternary (nickel, cobalt, manganese composite) positive electrode materials etc
