Latest Patents

Noriya Ishida holds a patent for a novel primary or secondary battery that utilizes metallic gallium, gallium alloys, or gallium oxide as the active material for the negative electrode. This innovation presents a unique advantage, as gallium has an electrochemical equivalent of 23.24, which is lower than that of zinc and cadmium. This characteristic allows for a larger capacity per unit mass when used in batteries. The reaction potential of gallium indicates that a high-potential battery can be developed, which is further enhanced by the absence of dendrite formation during electrodeposition. Additionally, gallium's high hydrogen overvoltage contributes to limited self-discharge and presents fewer environmental issues due to its non-toxic nature.
