Abstract: A method for manufacturing mixed oxide powders including the steps (a) producing a raw material mixture, (b) bringing the raw material mixture into a hot gas flow for the thermal treatment in a reactor, (c) forming particles of the mixed oxide powder, and (d) bringing the particles of the mixed oxide powder which are obtained in the step (b) and (c) out of the reactor, wherein the raw material mixture is manufactured in the form of a solution or suspension of at least one salt and/or salt mixture of at least one compound of the elements lithium, nickel and/or manganese, as well as a mixed oxide powder which is manufactured according to this method.

Abstract: The invention relates to a process for producing an electrochemical cell, particularly a solid-electrolyte battery, wherein a paste or foil is applied to each of the opposing surfaces of a solid electrolyte that form the respective anode and the respective electrode, and organic components within the pastes or foils are expelled in a heat treatment under an inert or reducing atmosphere. Subsequent to this, in a further stage, a fusional connection is produced by sintering between the anode and the solid electrolyte and between the cathode and the solid electrolyte. Here, the solid electrolyte is formed with an oxidic material conductive for lithium ions, the anode with a first lithium-containing chemical compound, particularly lithium titanate, and carbon, and the cathode with a second lithium-containing chemical compound, particularly a lithium metal phosphate, and carbon, to give a three-layer electrochemical cell construction devoid of organic components.

Abstract: The invention relates to a composite cathode layered structure for solid-state batteries on a lithium basis, in which a barrier layer (3), which is formed from an electronically conductive material, which is not conductive to lithium ions, is formed on a surface of a cathode layer (1) which is formed with an active material which is suitable for temporarily storing lithium ions, a material which is conductive to lithium ions and electrons. On the opposite surface of the cathode layer (1) there is a further layer (2) which forms a barrier layer or a solid electrolyte and is formed from a material which is electronically non-conductive and is conductive to lithium ions, and is connected in a materially joined fashion to the respective surface of the cathode layer (1) as a result of sintering.

Abstract: In the electrical energy storage element in accordance with the invention, a plurality of electrochemical cells that are each formed with a cathode and an anode as electrodes and an electrolyte are arranged stacked above one another. They are enclosed at one side by a top plate formed from an electrically conductive material, in particular aluminum, and at the oppositely disposed side by a base plate formed from an electrically conductive material, in particular aluminum. The base plate is coated by a cathode or by an anode and the cover plate is coated in a complementary manner by an anode or by a cathode. The anodes and cathodes are each formed at oppositely disposed surfaces of an electrically conductive carrier film which preferably comprises aluminum, copper, steel or an electrically conductive plastic.
