Latest Patents

One of Ukita's latest patents involves a novel battery design. According to this embodiment, the battery includes an exterior container, a lid member, a plurality of electrode groups, a first lead, a second lead, and an electrode terminal. The lid member effectively closes an opening of the inner cavity of the exterior container, where the plurality of electrode groups is stored. A first current collecting tab protruding toward the lid member in a first electrode is joined with the first lead, while a second current collecting tab in a different second electrode is joined with the second lead, which is separate from the first lead. Both leads are connected to the electrode terminal exposed on the outer surface of the lid member.

Another significant patent pertains to an electroplating method and device. This method generates a metal film on a cathode surface by applying a negative potential to both the anode and cathode in a reaction bath. The process involves mixing a plating solution containing plated metal ions, an electrolyte, and a surface-active agent with a supercritical fluid. A current is then applied in a concentration of the supercritical fluid and a cathode current density, ensuring that the polarization resistance obtained from a cathode polarization curve is larger than before the supercritical fluid is mixed.
