Abstract (en)

[origin: WO2018113807A1] The invention relates to a lithium ion solid-state battery, comprising an anode, a cathode and a solid electrolyte, wherein the solid electrolyte has a layer thickness between 100 μm and 800 μm, preferably between 200 μm and 500 μm and especially advantageously between 200 μm and 300 μm. The lithium ion solid-state battery comprises a mixture of lithium vanadium phosphate (LVP), lithium aluminum titanium phosphate (LATP), and lithium titanium phosphate (LTP). In order to produce a lithium ion solid-state battery according to the inventon, a pre-calcined electrolyte powder is pressed and is sintered to form an electrolyte layer. Then, the electrodes are applied and sintered on both sides. Before an electrode layer is applied, at least one intermediate layer can optionally be applied to the solid electrolyte for improved attachment of the electrode layer to the solid electrolyte. Preferably all common standard printing processes, such as screen printing, offset printing, or ink-jet printing, can be used to apply the layers.
