Jo , as modified by Miyahisa and Sakai, does not explicitly teach wherein the fuse portion further comprises extension holes extending from ends of the fuse hole toward an outer side of the first current collector plate, and the extension holes are in parallel. However, Sakai teaches a current collector to prevent or suppress exfoliation of welded portions by giving elasticity to contact portion of current collector joined to armoring can to relieve vibration or shock applied to the welded portions with elastic deformation of this contact portion (see e.g., Abstract). Sakai teaches the negative electrode current collector 61 with the two arc-shaped 62a extending in the circumferential direction and four radial slits 62b extending in the radial direction (“wherein the fuse portion further comprises extension holes extending from ends of the fuse hole toward an outer side of the first current collector plate”), and these slits 62a and 62b form a bridging piece 61b that acts as a contact portion (see e.g., paragraph [0063]), wherein the slits 62b extend toward each other in parallel (“the extension holes are in parallel”) (see e.g., Figure 9C). Therefore, it would have been obvious before the effective filing date of the claimed invention that one of ordinary skill would modify the first current collector of Jo , as modified by Miyahisa and Sakai , to have radial slits extending from the arc-shaped slits between the terminal portion and the edge that extend towards each other, as taught by Sakai, in order to prevent or suppress exfoliation of welded portions by giving elasticity to contact portion of current collector joined to armoring can to relieve vibration or shock applied to the welded portions with elastic deformation of this contact portion (see e.g., Abstract). Regarding claim 36 , Jo , as modified by Miyahisa , teaches the instantly claimed invention of claim 31, as previously described. Jo , as modified by Miyahisa , does not explicitly teach wherein the first current collector plate comprises a plurality of buffer slits located outside the fuse portion to be symmetrical to each other with respect to the fuse portion. However, Sakai teaches a current collector to prevent or suppress exfoliation of welded portions by giving elasticity to contact portion of current collector joined to armoring can to relieve vibration or shock applied to the welded portions with elastic deformation of this contact portion (see e.g., Abstract). Sakai teaches the current collector has a disc-shaped current collector body 61a with two arc-shaped slits 61a extending in the circumferential direction (“wherein the first current collector plate comprises a plurality of buffer slits located outside the fuse portion to be symmetrical to each other with respect to the fuse portion”) (see e.g., paragraph [0063] and Figure 9C). Therefore, it would have been obvious before the effective filing date of the claimed invention that one of ordinary skill would modify the first current collector of Jo , as modified by Miyahisa , to have arc-shaped slits between the terminal portion and the edge, as taught by Sakai, in order to prevent or suppress exfoliation of welded portions by giving elasticity to contact portion of current collector joined to armoring can to relieve vibration or shock applied to the welded portions with elastic deformation of this contact portion (see e.g., Abstract). Regarding claim 37 , Jo , as modified by Miyahisa and Sakai, teaches the instantly claimed invention of claim 36, as previously described. Sakai teaches the current collector has a disc-shaped current collector body 61a with two arc-shaped slits 61a extending in the circumferential direction (“wherein a buffer slit of the plurality of buffer slits has a ‘U’ shape”) (see e.g., paragraph [0063] and Figure 9C). Regarding claim 38 , Jo , as modified by Miyahisa , teaches the instantly claimed invention of claim 31, as previously described. Jo , as modified by Miyahisa , does not explicitly teach wherein the fuse portion comprises one or more fuse holes, and the fuse holes are located concentrically with respect to a center of the first current collector plate. However, However, Sakai teaches a current collector to prevent or suppress exfoliation of welded portions by giving elasticity to contact portion of current collector joined to armoring can to relieve vibration or shock applied to the welded portions with elastic deformation of this contact portion (see e.g., Abstract). Sakai teaches the current collector has a disc-shaped current collector body 61a with two arc-shaped slits 61a extending in the circumferential direction (“wherein the fuse portion comprises one or more fuse holes, and the fuse holes are located concentrically with respect to a center of the first current collector plate”) (see e.g., paragraph [0063] and Figure 9C).
