Latest Patents

Nakamura's latest patents include a negative-electrode plate and a cylindrical cell that incorporates this innovative design. The negative-electrode plate is intended for use in a cylindrical cell, which is structured to enhance the efficiency of energy storage. This design features a first negative-electrode part that faces the positive-electrode plate, with a separator in between, and a second negative-electrode part that forms the innermost circumference of the electrode body. The second part has a lower density of negative-electrode active material compared to the first, optimizing performance.

Another notable patent is for a negative electrode specifically designed for nickel-hydrogen rechargeable batteries. This strip-shaped negative electrode consists of a core body covered by a negative mixture layer containing hydrogen-storage alloy particles. The design ensures that both sides of the main section face the positive electrode, with the separator intervening, while the outermost and innermost circumferential portions protrude and face the positive electrode on one side only. The hydrogen-storage alloy particles in these protruding sections have a larger average diameter than those in the main section, enhancing the battery's overall efficiency.
