Latest Patents

Yoshihiko Hase holds a patent for a production process of carbonaceous material and battery. The patent outlines a method that involves several steps, including subjecting a vacuum distillation residual pitch to heat treatment until the content of quinoline-insoluble components reaches 50 to 85 wt. %. This process converts the pitch into a mesophase pitch, which is then ground into fine particles with an aspect ratio not greater than 2. The ground product undergoes oxidation treatment, followed by carbonization or graphitization treatment. The resulting carbonaceous material is utilized in the negative pole of a lithium-ion secondary battery.
