Latest Patents
One of Nonaka's latest patents focuses on an electrode metal material designed for use in batteries and capacitors that come into contact with non-aqueous electrolytes. This invention provides a valve metal material that effectively decreases the internal resistance of capacitors. The electrode metal material consists of a valve metal substrate embedded with numerous carbon particles on its surface. These carbon particles are fixed to the valve metal surface, ensuring they remain exposed. The material is further coated with an activated carbon layer, allowing it to function as a double-layer electrode for electric double-layer capacitors. This innovative configuration ensures that even if the valve metal surface oxidizes, the internal resistance of the electrode remains stable, leading to decreased internal resistance and increased capacitance in the capacitor.
