Latest Patents

One of her latest patents is titled "Electric double layer capacitor and method of manufacturing the same." This invention involves the formation of a pair of conductive layers on electrically insulating substrates. The design includes polarizable electrodes sandwiched between these conductive layers, with an ionically conducting separator interposed. The polarizable electrodes are preferably made of an activated carbon/polyacene composite. This innovation allows for the creation of multiple elements that are electrically insulated on the same substrate, enabling a high breakdown voltage and a low height for the capacitors.

Another significant patent is "Activated carbon/polyacene composite and process for producing the same." This composite contains activated carbon powder or fiber with a specific molar ratio of hydrogen to carbon. It provides enhanced capacitance per unit volume and reduces the equivalent series resistance of electric double-layer capacitors without compression. The composite is produced by mixing activated carbon with a thermosetting resin powder and subjecting it to heat treatment in a non-oxidizing atmosphere.
