The automotive industry is undergoing a transformative shift toward the adoption of electric vehicles (EV) and is investing significantly in the research and development (R&D) of its battery technology and components. The energy density and weight of the battery are the major factors that determine the designing and manufacturing cost of an electric vehicle. The conventional lithium-ion (Li-ion) battery technology has been in existence since 2000s and has found its applications in various sectors, namely electronics & automotive industry, and energy storage systems. However, key limitations of the li-ion batteries such as high flammability, risk of leakage, high cost, and ageing have propelled the researches to develop better battery chemistries such as solid-state batteries (SSB).
