  • All-solid-state sodium-ion secondary battery (under development)

    We have newly developed a glass-ceramic cathode material, in addition to anode material, using sodium ions, which has resulted in the world’s first all-solid-state sodium-ion secondary battery. The battery’s use of sodium, which is a cheap and abundant resource, and its high stability, offer practical-level performance and great promise for the future. The product is under development and we hope to commercialize it as soon as possible. (写真:Test charging of a smartphone using the sodium-ion battery)

Glass Fiber Recycling

Recycling technologies have long been used in Japan in the glass fiber business to produce fiber used in various applications such as automobiles, households appliances, and everyday items.

When used as a composite reinforcing material, glass fibers are bundled together and surface-treated with organic material, both as protection and to enable the fibers to bond with resin. That finish poses a problem, causing many glass fiber manufacturers to treat loss and waste generated in the manufacturing process as industrial waste.

We have eliminated the finish, so we can grind the glass fiber and turn it entirely into reusable material. Also, we collect the dust in the vapor generated from molten glass, whose main component is boric acid, and reuse it in glass raw material—a technology established in the 1980s. These technologies also help to conserve resources and clean exhaust gas.
