%X All-Solid-State Batteries (ASSB) are considered to be one of the most promising future battery technologies due to the prospect of increased safety and energy density. ASSB can be categorized into three main classes: Polymers, Sulfides and Oxides, which are the focus of this work. Ceramic oxides, among others, are suitable to replace current liquid electrolytes of Lithium-ion batteries (LIBs), with the advantage of being the only solid electrolyte (Li7La3Zr2O12, LLZO) that is stable to Li metal. Li metal as an anode material provides a higher energy density in the battery and can overcome the foreseeable limits of liquid electrolytes. In addition, ceramic oxide solid electrolytes increase safety due to the high thermal stability of ceramic materials. Disadvantages of LLZO are the high processing cost and energy requirements, leading to high embodied energy due to the multiple long calcination times at high temperatures. Also, LLZO production requires raw materials beyond Li, Co, Ni and Mn, which are well-known from the cathode materials in LIBs. Notably, Ta, and Ga are listed as critical raw materials. This is one of the main reasons why recycling is important for both current LIBs and future ASSB batteries. The current EU directive requires a recycling rate of 70
