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.
