Latest Patents

Mugima's latest patents include a negative-electrode plate and a cylindrical cell that incorporates this design. The negative-electrode plate is intended to be laid over a positive-electrode plate with a separator interposed between them. This configuration is rolled to form a cylindrical electrode body, which houses the positive-electrode plate. The design features a first negative-electrode part that faces the positive-electrode plate on either side, and a second negative-electrode part that forms the innermost circumference of the electrode body. Notably, the second part has a lower density of negative-electrode active material compared to the first part.

Another significant 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 includes a main section that faces the positive electrode, as well as protruding outermost and innermost circumferential portions. These portions contain hydrogen-storage alloy particles with a larger average diameter than those in the main section, enhancing the battery's efficiency.
