摘要： A battery case is made by cutting from a blank case of a bottomed cylindrical battery case having an unwanted portion at an opening portion the unwanted portion from the case wall in the circumferential direction by a blade. The cutting of the case wall is performed so as to render a cutting-end portion higher than a cutting-start portion. Thus, re-cutting of the cutting-start portion by the blade after it has already completed one rotation can be avoided. As a result, the generation of thread-like chips from re-cutting of the cut surface can be avoided.

摘要： A metal can blank having a shape surrounded by n external tangents, n partial arcs or partial lines, and 2n linear or arc-shaped connect lines is used to produce a metal can. Each external tangent is a line shorter than one side of a regular n-gon circumscribed about a circle, with the midpoint being a point of contact between each of the n sides of the regular n-gon and the circle. Each partial arc is a part of the circle positioned between the adjacent external tangents in the circumferential direction of the circle. Each partial line is a line connecting both ends of the partial arc. Each connect line is a line connecting one end of the external tangent with the most adjacent end of the partial arc or partial line. The material yields, productivity, etc. of such metal cans are significantly improved, and high quality metal cans can be obtained.

摘要： An objective is to improve the mechanical strength and the durability of a current collector for a non-aqueous electrolyte secondary battery and to allow an active material layer to be efficiently carried on the surface of the current collector with high adhesion. This objective is achieved with the use of a pair of processing means being disposed such that the surfaces thereof are in press contact with each other to form a press nip for passing a sheet material therethrough and having a plurality of recesses formed on the surface of at least one of the processing means, by passing a metallic foil for current collector through the press nip between the processing means to perform compression, thereby to form a plurality of projections on at least one surface of the metallic foil for current collector by partial plastic deformation associated with the compression.
