ABSTRACT=<p>The review presents an overview of the recent advances in inorganic solid lithium ion conductors, which are of great interest as solid electrolytes in all-solid-state lithium batteries. It is focused on two major categories: crystalline electrolytes and glass-based electrolytes. Important systems such as thio-LISICON Li<sub>10</sub>SnP<sub>2</sub>S<sub>12</sub>, garnet Li<sub>7</sub>La<sub>3</sub>Zr<sub>2</sub>O<sub>12</sub>, perovskite Li<sub>3</sub><italic><sub>x</sub></italic>La<sub>(2/3)−</sub><italic><sub>x</sub></italic>TiO<sub>3</sub>, NASICON Li<sub>1.3</sub>Al<sub>0.3</sub>Ti<sub>1.7</sub>(PO<sub>4</sub>)<sub>3</sub>, and glass–ceramic xLi<sub>2</sub>S⋅(1 − <italic>x</italic>)P<sub>2</sub>S<sub>5</sub> and their progress are described in great detail. Meanwhile, the review discusses different on-going strategies on enhancing conductivity, optimizing electrolyte/electrode interface, and improving cell performance.</p>
