Abstract: In a cathode paste (1) for producing a cathode of a lithium-ion cell, the cathode paste comprises, as an active material, a metallic lithium mixed oxide selected from the group consisting of a lithium-nickel-manganese-cobalt mixed oxide represented by the formula LiNixMnyCozO2, wherein x+y+z=1 and x?0.6, and a lithium-nickel-cobalt-aluminum mixed oxide of the formula LiNixCoyAlzO2, wherein x+y+z=1 and x?0.8, and mixtures with said lithium mixed oxides. Further, the cathode paste comprises a polyvinylidene difluoride-based electrode binder. Further, the cathode paste comprises a solvent comprising N-methylpyrrolidone and/or N-ethylpyrrolidone. Furthermore, the solvent comprises an organic additive component suitable for neutralizing hydroxide ions and having a boiling point at atmospheric pressure in the range from 50° C. to 210° C.

Abstract: A ribbon-shaped electrode has a ribbon-shaped current collector and a coating with electrode material on one or both sides, wherein the ribbon-shaped current collector includes a first and a second longitudinal edge, the first longitudinal edge is designed as a contact edge, the contact edge is used for electrical contacting of the electrode and the contact edge is not coated with the electrode material, the second longitudinal edge is formed as a supporting edge which is not coated with the electrode material, and the width of the supporting edge is at most 99% of the width of the contact edge.

Abstract: A secondary lithium battery includes (a) a housing enclosing an interior space, and (b) a composite body arranged in the interior space and including at least one positive electrode, at least one negative electrode and at least one separator, wherein (c) the housing includes a metal housing part having an inner side pointing into the interior space and an outer side pointing away from the interior space, and (d) the metal housing part includes: a first layer consisting of aluminium or an aluminium alloy that forms the inner side of the metal housing part, and in direct contact with the first layer, a second layer consisting of nickel or a nickel alloy that forms the outer side of the metal housing part.

Abstract: A process of producing positive electrodes for lithium ion batteries including providing a composition containing at least one active material that takes up and releases lithium ions during charging and discharging of a lithium ion battery, at least one electrode binder, at least one conductivity improver and water as a solvent and/or suspension medium; providing a current collector having a surface composed of aluminium or of an aluminium alloy; and applying the composition to the surface of the current collector, wherein the composition is alcalinically modified by addition of at least one base so that the pH of the composition is increased before it is applied to the surface of the current collector.
