Abstract:

Solid-state lithium-ion batteries have become the promising development direction of power batteries due to their high energy density and excellent safety performance. This paper reviews the component and characteristics of solid-state lithium-ion batteries in detail, as well as the types and research progress of solid electrolytes. Moreover, this review also briefly describes the current status of solid-state lithium-ion batteries, and focuses on the garnet-type lithium lanthanum zirconium oxide (Li7La3Zr2O12-based) solid electrolytes which have outstanding advantages in lithium ion conductivity and interface regulation. As one important component of all-solid lithium ion power batteries, the garnet-type Li7La3Zr2O12-based solid electrolytes have good ionic conductivity at room temperature, excellent metal-lithium interface compatibility, and outstanding stability under application environment. The breakthrough and development of solid electrolytes will inevitably provide a huge thrust for the future development of solid-state lithium-ion power batteries and even electric vehicles.

Key words: electric vehicles, solid state lithium ion batteries, solid electrolytes, lithium lanthanum zirconium oxide (Li7La3Zr2O12), safety
