Latest Patents

One of Okada's latest patents involves a nonaqueous secondary electrolytic battery. This innovative battery design features an electricity-generating element formed by spirally winding a laminate of a positive electrode plate, a separating material, and a negative electrode plate. The electrolytic solution impregnates the separating material, if it serves as a separator. The electricity-generating element is sealed within a battery case made from a resin-laminated sheet that includes a metal layer as a barrier. The design allows for only a pair of lead terminals to be drawn to the exterior of the battery case. The resin sheet consists of an oriented resin layer laminated on both surfaces of the metal layer, with inner heat-fused layers that are opposed and fused together. A molten and solidified resin mass protrudes from the inner end of the welded portion toward the inner space of the battery by 0.1 mm or more. Alternatively, the welded portion can be thinner at the outer end than at the inner end.
