Abstract: Conventional lithium-ion secondary batteries have been widely used in portable electronic devices and are now developed for large-scale applications in hybrid-type electric vehicles and stationary-type distributed power sources. However, there are inherent safety issues associated with thermal management and combustible organic electrolytes in such battery systems. The demands for batteries with high energy and power densities make these issues increasingly important. All-solid-state lithium batteries based on solid-state polymer and inorganic electrolytes are leak-proof and have been shown to exhibit excellent safety performance, making them a suitable candidate for the large-scale applications. This paper presents a brief review of the state-of-the-art development of all-solid-state lithium batteries including working principles, design and construction, and electrochemical properties and performance. Major issues associated with solid-state battery technologies are then evaluated. Finally, remarks are made on the further development of all-solid-state lithium cells.

Key words: energy storage, all-solid-state lithium-ion cell, solid electrolyte, interface modification
