Compared with conventional lithium-ion batteries, all-solid-state lithium batteries (ASSLBs)
based on inorganic solid electrolytes (ISEs) are relatively new research hotspots, which can
overcome tough challenges in conventional lithium-ion batteries, such as potential
combustion accidents resulted from flammable liquid electrolyte solvent, low energy density,
and fussy manufacturing process. In this review, we focus on the ionic conductivity and
stability of ISEs by discussing defect chemistry, ion-doping or elemental substitution, ion …
