Abstract: | So far, electrolytes used in the commercialized lithium ion batteries are mainly based on liquid organic solvents, including ethylene carbonate, methyl-carbonate and propylene carbonate. During the charge/discharge process, decomposition of the electrolyte, uncontrollable formation of lithium dendrites and the leakage of the liquid electrolyte may occur, leading to the low stability and safety issues of the lithium ion batteries. Inorganic solid electrolytes have become a hot topic in the field of energy storage due to many advantages, such as high thermal stability, high electrochemical stability, being compatible with higher potential cathode materials, safety and environmental friendliness. The development of inorganic solid electrolytes with high ion conductivity is the focus and also challenge. In this paper, the last development in ion conductivity of inorganic solid electrolytes, such as LiPON, GARNET, Perovskite and LISICON are reviewed, and the application of these electrolytes in solid-state lithium batteries is summarized. |
