Background

Rapid growth of the electric vehicle (EV) market requires the development of LIBs (lithium-ion batteries) with higher energy and power densities, better safety, and longer lifespan. To enhance energy density and overcome the safety issues of LIBs, all-solid-state batteries employing an inorganic solid-state electrolyte (SSE) have been promoted as a breakthrough technology. However, current development of all-solid-state batteries is still at an early stage due to a number of challenges related to chemical, structural, and mechanical stabilities as well as charge transport limitations in the composite cathode.
