    摘要： A method for producing a negative electrode for a lithium ion battery includes the steps of: (1) preparing a negative electrode plate and a negative electrode lead, the negative electrode plate comprising a current collector and a thin-film negative electrode active material layer including an alloyable active material; (2) clamping the negative electrode plate and the negative electrode lead between a pair of welding jigs comprising a first plate and a second plate, in such a manner that a surface of the thin-film negative electrode active material layer and a surface of the negative electrode lead overlap and that a welding region including a welding end face is exposed; and (3) generating an arc discharge toward the welding region to melt the welding region. The welding jigs have, along the welding region, a shape which restricts expansion of the volume of the welding region due to the arc discharge.

    摘要： A current collector including a substrate, a plurality of projections, and a chipped portion is provided. The substrate is a metal sheet. The projections are formed on the surface of the substrate. The chipped portion is an aggregate of two or more, preferably 2 to 100 of minute projections. The minute projections are formed on the substrate surface, and are the protrusions having the height of below 35% of the average height of the projections. By forming an electrode active material layer on the face of the current collector where the projections are formed to make an electrode, the detachment of the electrode active material layer, and the spread of the detachment are significantly curbed. By using this electrode, a non-aqueous electrolyte secondary battery which have high battery capacity and energy density, excellent charge and discharge cycle characteristics, and which is capable of keeping a high-output stably for a long period of time can be obtained.
