Six Core Technologies

Particle Sphering Technology

Particle sphering technology is used to control the shape by controlling particle formation. Using this technology, we have succeeded in increasing the density of positive electrode material, thereby contributing to higher performance batteries.

  • Irregular particles
  • Spherical particles

Multi-element Co-precipitation Technology

Multi-element co-precipitation technology is used to co-precipitate various elements at the atomic level. In conventional technology, even when multiple elements seem evenly mixed, they are actually unevenly distributed at the atomic level in most cases. We apply our unique multi-element co-precipitation technology during the reaction process, allowing the elements to be distributed and co-precipitated evenly inside the particle.

  • Status of Co-precipitated Multiple Elements

Particle Size Control Technology

Particle Size Control Technology is used to produce particles with various diameters by changing the reaction conditions to produce compounds. Through the use of this technology, particle core generation and particle growth can be controlled, enabling us to freely control the size of particles.

  • Particle size:Large
  • Particle size:Medium
  • Particle size:Small

Crystal Structure Control Technology

Crystal structure control technology is used to change the crystal structures of compounds having the same chemical formula by changing the reaction conditions. This technology allows us to control the crystal structures, thereby contributing to the success in producing compounds that suit various applications of batteries.

  • FWHM (Full Width Half Minimum) in X-ray Diffractometer

Surface Coating Technology

Surface coating technology is used to form a cobalt hydroxide film on the surface of nickel hydroxide, while controlling the crystal structure, degree of oxidation, and other properties of cobalt hydroxide. This has contributed to realizing increased capacity and power of batteries.

Chemical Oxidation Technology

Chemical oxidation technology is used to produce unique forms of chemical compounds by controlling conditions such as reaction temperature, density and loading method. Now that chemical oxidation can be applied to the surface or the inside of particles, we can successfully produce chemical compounds suitable for various applications of batteries.
