Latest Patents
One of his latest patents is titled "Carbon material and method of making same." This invention provides a new carbon material for electric double-layer capacitors, which exhibits characteristics that differ significantly from traditional activated carbon. The capacitor operates on a unique mechanism that improves performance, including capacitance. The design features polarized electrodes immersed in an organic electrolyte, made from nonporous carbon with graphite-like crystallites. The intercalation of electrolyte ions occurs during the first charging cycle, leading to the formation of electric double layers in subsequent cycles.
Another important patent is related to an electric double-layer capacitor that utilizes nonporous carbon as the active material for both positive and negative electrodes. This nonporous carbon is characterized by multiple layers of graphene with a specific interplanar spacing. The electrodes are impregnated with an electrolyte solution, which can either be a liquid electrolyte with a planar molecular structure or a solution dissolved in an organic solvent. This innovative approach enhances the overall efficiency and effectiveness of the capacitor.
