Latest Patents

One of Mitamura's latest patents is a method of manufacturing a metal-air battery. This method involves a first step that includes stacking an exterior body, a water-repellent film, and a positive electrode in a specified order. The process begins with a fusing step that fuses the exterior body and the water-repellent film, followed by a compression step that compresses the water-repellent film and the positive electrode. After completing the first step, a portion of the exterior body is removed from inside the fusing portion to create an opening, such as an air inlet, in the exterior body. Another notable patent involves the design of an air electrode, which consists of a current collector, a catalyst layer, and a water-repellent membrane arranged in that order. The catalyst layer features a first face in contact with either the current collector or the water-repellent membrane, and a second face in contact with the other. This design includes a plurality of through holes that allow communication between the two faces, with each hole having a constriction that is smaller than the opening diameters on either face.
