Estimating the term…
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.
A composite cathode layer structure for lithium-based solid-state batteries, wherein a barrier layer (3) which is composed of an electronically conducting material which does not conduct lithium ions is present on a surface of a cathode layer (1) comprising an active material suitable for the temporary storage of lithium ions, a material which conducts lithium ions and electrons, and a further layer (2) which forms a barrier layer or a solid electrolyte and is composed of a material which is electronically nonconductive and conductive for lithium ions is present on the opposite surface of the cathode layer (1) and these layers are joined to the respective surface of the cathode layer (1) by material-to-material bonding as a result of sintering.
