Latest Patents
Mogami's latest patents include a novel carbon material and a method of making the same. This invention provides a unique carbon material for electric double-layer capacitors, which exhibits characteristics that are entirely different from traditional activated carbon. The capacitor developed from this material operates on a mechanism distinct from that of conventional electric double-layer capacitors, resulting in improved performance and capacitance. The design features polarized electrodes immersed in an organic electrolyte, made from nonporous carbon with crystallites of graphite-like carbon. The intercalation of electrolyte ions between the layers of the crystallites occurs during the first cycle of charging, leading to the formation of electric double layers and enhanced capacitance in subsequent cycles.
Another significant patent relates to an electric double-layer capacitor that utilizes positive and negative electrodes containing nonporous carbon as the active material. This nonporous carbon is characterized by multiple layers of graphene with an average interplanar spacing of 0.350 to 0.380 nm. The electrodes are impregnated with an electrolyte solution,
