Latest Patents
One of Hojo's latest patents is a processing device for nonaqueous electrolyte secondary batteries and its manufacturing method. This innovation involves melting and diffusing metallic foreign bodies that may be present in the electrodes before the initial charging process. The method includes placing electrodes wound with a separator between a cathode plate and an anode plate into a battery case filled with electrolyte. The electrolyte is allowed to permeate into the electrodes, and the battery is then subjected to a specific surface pressure for a defined period to ensure optimal performance.
Another notable patent is a method for producing lithium secondary cells. This method aims to inhibit the concentrated precipitation of metal impurities at the negative electrode, thereby reducing the likelihood of short circuits. The production process involves assembling the positive electrode, separator, and negative electrode, followed by impregnation with a nonaqueous electrolyte. The assembly is charged rapidly to achieve a high potential, allowed to stand briefly, and then discharged, ensuring a reliable and efficient battery.
