Process for producing an electrochemical cell, and electrochemical cell produced by the process

A process for producing an electrochemical cell, in particular a solid electrolyte battery, wherein

• a paste or sheet which in each case forms the respective anode and the respective electrode is applied to each of the opposite surfaces of a solid electrolyte and, in a heat treatment in an inert or reducing atmosphere, organic components which are present in the pastes or sheets are driven off and then, in a further stage, a material-to-material bond is produced between the anode and the solid electrolyte and between the cathode and the solid electrolyte by means of sintering;
• where
• the solid electrolyte comprising a lithium ion-conductive and oxidic material, the anode comprising a first chemical compound, in particular lithium titanate, and carbon and the cathode comprising a second lithium-containing chemical compound, in particular a lithium-metal phosphate, and carbon are formed, so that
• an electrochemical cell structure which has in each case three layers and in which no organic components are present is obtained.
