The developments, challenges, and prospects of solid-state Li-Se
Li-chalcogen batteries with the high theoretical energy density have been received as one of most promising secondary lithium-ion batteries for next generation energy storage devices. Compared to solid-state Li-S batteries (S-LSBs) at the bottleneck of development, solid-state Li-Se batteries (S-LSeBs) have comparable volumetric energy density and fast reaction kinetics due to the
