摘要： The present invention relates to a sintering apparatus comprising a first and a second carbon-comprising thermally conductive substrate arranged at a distance from each other, thereby providing a space for receiving a substrate to be sintered, and provided between a third and a fourth thermally conductive substrate; and heating means for heating the third and/or the fourth thermally conductive substrate at a heating rate of at least 50 °C/s to a temperature between 750 °C and 1400 °C, thereby heating the first and/or the second thermally conductive substrate, respectively, wherein the third and the fourth thermally conductive substrate comprise, independently from one another, one or more metal nitride and/or metal oxide.

摘要： The present invention discloses a method for producing a multilayer solid state electrolyte (SSE) comprising alternating dense layers and porous layers, wherein the number of layers is at least two, the method comprising: addint a first compound comprising one or more of an alkali metal and/or an alkaline earth metal and a first binder to a first solvent, thereby obtaining a first mixture; adding a second compound comprising one or more of an alkali metal and/or an alkaline earth metal, a second binder, and a pore-forming compound to a second solvent, thereby obtaining a second mixture; film-casting the first mixture and the second mixture on a substrate until the number of layers is obtained, thereby obtaining a green (multilayer) structure; debinding and sintering the green (multilayer) structure, thereby obtaining the multilayer SSE. The invention further discloses a multilayer SSE obtained by methods of the invention, and a solid state battery comprising such a SSE.
