    摘要： A nonaqueous electrolyte secondary cell includes a rolled-up electrode unit composed of a positive electrode, a negative electrode and a separator interposed therebetween, and a negative electrode current collector plate and a positive electrode current collector plate joined to the respective ends of the electrode unit. The negative electrode collector plate is joined to an edge of the negative electrode projecting at one of the opposite ends of the electrode unit. The collector plate has a two-layer structure of a copper layer made of copper or an alloy consisting predominantly of copper, and a metal layer made of a metal not forming an intermetallic compound with lithium and having a lower laser beam reflectivity than copper or an alloy consisting predominantly of the metal. The collector plate has its copper layer contacted with the edge of the negative electrode and welded thereto with a laser beam.

    摘要： For use in lithium secondary cells, a positive electrode terminal 51 and a negative electrode terminal 81 are given an enhanced mechanical strength to improve the reliability of electrical connection between the cell and an external circuit, while the formation of oxide film on these terminals is inhibited to suppress the discharge voltage drop of the cell. To give these advantages to the lithium secondary cell embodying the invention, the positive electrode terminal 51 is formed from an aluminum alloy containing magnesium and silicon in a combined amount of at least 1.0 wt. % as additive elements, and the negative electrode terminal 81 is formed by plating a substrate of oxygen-free copper with nickel.

    摘要： A nonaqueous electrolyte secondary cell comprises a rolled-up electrode unit 2 composed of a positive electrode 23, a negative electrode 21 and a separator 22 interposed therebetween, and a negative electrode current collector plate 3 and a positive electrode current collector plate 30 joined to the respective ends of the electrode unit 2. The negative electrode collector plate 3 is joined to an edge of the negative electrode 21 projecting at one of the opposite ends of the electrode unit 2. The collector plate 3 has a two-layer structure comprising a copper layer 31 made of copper or an alloy consisting predominantly of copper, and a metal layer made of a metal not forming an intermetallic compound with lithium and having a lower laser beam reflectivity than copper or an alloy consisting predominantly of the metal. The collector plate 3 has its copper layer 31 contacted with the edge of the negative electrode 21 and welded thereto with a laser beam. This improves the weldability of the collector plate 3 to the rolled-up electrode unit 2 to achieve a high current collecting efficiency.

    摘要： A secondary cell comprises a gastight can 1 having a cylinder 11 and a lid 12 fixed to an opening portion of the cylinder, and a secondary cell element accommodated in the can 1. The lid 12 is fixedly provided with a gas vent closure 4 in the form of a disk and having a diaphragm 42 openable upon the internal pressure of the can 1 exceeding a predetermined value. The gas vent closure 4 has an outer peripheral portion welded to an opening edge defining a through bore 14 formed in the lid 12. The lid 12 is formed in a front surface thereof with a circumferential groove 5 surrounding the welded portion of the gas vent closure 4, and a diminished portion 51 is provided between the groove 5 and the welded portion for reducing the sectional area of a heat flow path for the heat of welding to pass therethrough. The lid 12 thus constructed makes it possible to weld the vent closure 4 to the lid 12 free of defects such as pinholes or cracks.
