Latest Patents

One of Fukuda's latest patents is for a prismatic battery. This invention features a sealing plate with weld-attached edges that close off an opening in a metal case. The sealing plate includes an electrode rivet that passes through an electrode hole, ensuring an electrically insulating attachment with an insulating gasket. The battery case houses an electrode group, with either the positive or negative electrode plate connected to the electrode rivet. Additionally, the sealing plate has a reinforcement rib that is thicker than the rivet region, providing structural integrity.

Another significant patent is a method of manufacturing a battery containing a non-circular spiral electrode unit. This method involves forming a true circular or elliptical cylindrical electrode unit by winding positive and negative electrode plates with a micro-porous polymer film separator. The cylindrical electrode unit is then pressed into a non-circular spiral shape and inserted into an external case to create the battery. The separator gurley value of the pressed non-circular spiral electrode unit is carefully controlled to ensure optimal performance.
