All-solid-state lithium batteries could address a number of the shortcomings of conventional lithium-ion batteries in advanced applications such as in electric vehicles, which demand high energy densities, fast charging, and long cycle lives. However, the solid electrolyte comes with its own challenge; the interface between the positive electrode and solid electrolyte shows a large electrical resistance whose origin is not well understood.
