Abstract

The invention relates to the field of lithium batteries, in particular to a solid-state electrolyte, a lithium battery cell and a lithium battery. The solid-state electrolyte is an anti-perovskite solid-state electrolyte, and includes one or more super base clusters selected from Li3Se+, Li3S+ and Li3O+ and one or more super halogen clusters selected from BH4-, AlH4-, BF4-, FeH4-, CoH4- and NiH4-.Therefore, the solid-state electrolyte has an electrochemical window above 5V and better adhesion and flexibility, and has better interfacial wettability and interfacial adhesion when contacting an electrode layer. Because the Se atoms are weakly bound to Li+ in the structure of the solid-state electrolyte, Li ions are easy to migrate, and better conductivity can be obtained. Furthermore, based on the structural characteristics of the solid-state electrolyte, the solid-state electrolyte has the advantages of high shear modulus, high Young's modulus and capability of inhibiting the growth of lithium dendrites.

Description

【Technical field】 [0001] The invention relates to the field of lithium batteries, in particular to a solid electrolyte, a lithium battery cell, and a lithium battery. 【Background technique】 [0002] Compared with traditional liquid electrolytes, all-solid electrolytes have the advantages of high mechanical strength and good safety. However, except for sulfide, the existing solid-state electrolyte systems have low lithium ion conductivity, and generally the ion conductivity at room temperature is less than 10. -3 S / cm, therefore, sulfide solid electrolyte materials have always been a research hotspot. However, the sulfide solid electrolyte is very sensitive to water and air, and the solid electrolyte material in the prior art has a large interface resistance after contacting the positive and negative electrode materials, resulting in a short cycle life. [0003] Therefore, it is urgent to provide a technical solution of a sulfide solid electrolyte with a longer cycle life a...
