Li-ion batteries (LIBs) constitute a technological breakthrough with a large-scale impact on our societies. The current state of the art LIB is highly optimized and its density is close to the theoretical one, however, a next generation battery with higher capabilities can constitute a step further towards decreasing the reliance on fossil fuels. All-Solid-State Battery (ASSB) resembles a potential candidate for the upcoming energy storage devices. ASSBs may not just be superior with larger energy density and power performance because it also hinders (theoretically) dendrite formation giving the possibility of using Li metal anodes. They also provide higher safety aspects since the inflammable carbonatebased liquid electrolyte is not used.
