摘要： The invention refers to a method and an apparatus (20) for manufacturing of a prismatic unilaterally open battery cell container (21). First an extruded container (41) is formed from a slug (38) by extrusion. The slug (38) consists of a uniform material. The extruded container (41) is then formed by a first ironing in a first ironing station (25) and by a second ironing in a second ironing station (28). During ironing the container is moved by a respective ironing ram (26, 29) only partly through an associated die tool (27, 30) and is reversed when reaching a reversal point (U). After the second ironing a remaining edge (82) of the obtained intermediate container (77) is separated, thereby the battery cell container (21) is obtained.

摘要： A nonaqueous electrolyte secondary battery includes a positive electrode, a negative electrode having a negative electrode active material, and a separator containing an electrolyte. The electrolyte includes an electrolyte salt, a nonaqueous solvent into which the electrolyte salt can be dissolved, a first additive selected from predetermined oxalate compounds and disulfonic acid ester compounds, and a second additive that has a reduction potential less than the reduction potential of the first additive. The second additive is selected from a group having vinylene carbonate, fluoroethylene carbonate, vinyl ethylene carbonate, 1, 3-propane sultone, 1, 4-butane sultone, 1, 3-propene sultone, succinonitrile, and adiponitrile.
