    摘要： A nonaqueous electrolyte secondary cell having a rolled-up electrode unit housed in a cell can and comprising a positive electrode and a negative electrode each formed by coating a surface of a striplike current collector with an electrode material. According to a first embodiment, the current collector of at least one of the positive electrode and the negative electrode comprises a plurality of current collector pieces 42 arranged along one direction and a PTC element 5 interconnecting each pair of adjacent current collector pieces 42. Alternatively with a second embodiment, at least one of the positive electrode and the negative electrode comprises a PTC element held between opposed faces of an uncoated portion of the current collector thereof and a base end portion of a current collector tab. The PTC element serves to prevent continuous occurrence of a current in excess of a predetermined value and realizes a high energy density.

    摘要： In a secondary cell comprising an electrode unit enclosed in a cell can and adapted to deliver electric power generated by the electrode unit via electrode terminal assemblies, each electrode terminal assembly comprises an electrode terminal member extending through a center hole in a lid of the can, an insulating seal member provided in the center hole of the lid around a screw shank of the electrode terminal member, and a nut screwed on the screw shank of the electrode terminal member projecting outward from can. The insulating seal member is in engagement with the can and the flange of the electrode terminal member and nonrotatable relative to the cell can and the flange, whereby the electrode terminal member is prevented from rotating with the nut when the electrode terminal assembly is fixed to the lid.
