Latest Patents
Among Hirofumi Sugikawa's latest patents is a groundbreaking method of manufacturing battery electrode substrates. This innovation involves forming concave and convex portions on a thin metal sheet's peripheral surface by applying a pressing force during the embossing process. The technique generates pores at the apex of each concave and convex portion, where burrs project outward from the peripheral edges of these pores due to the pressing force. Layering multiple metal sheets with these features allows for interlocking burrs, which integrate the sheets. This innovative design enables an active substance to be charged into the spaces between the upper-layer and lower-layer sheets through apertures located at the apex of each concave and convex portion.
