| Abstract: |
| All solid-state lithium batteries are considered the most promising energy storage device for the next generation due to their high energy density and safety. Solid-state electrolyte, as the core component of all solid-state lithium batteries, has attracted widespread attention due to its advantages such as non-flammability, high mechanical properties, and good compatibility with lithium metals. However, the low ionic conductivity, lithium dendrite growth and interface issues between the SSEs and electrodes limit the practical application of solid-state electrolytes in all solid-state lithium batteries. Therefore, in this review, the characteristic and research progress of oxide-based solid-state electrolyte, sulfide-based solid-state electrolyte, polymer-based solid-state electrolyte and composite solid-state electrolyte is summarized. And the problems of lithium dendrite growth and interface resistance faced by different types of solid-state electrolyte are described, and the corresponding optimization strategies are proposed. The current challenges for all solid-state electrolytes in all solid-state batteries are pointed out. At the same time, a brief introduction is given to the research process on the application of composite solid-state electrolytes in all solid-state lithium batteries. It is hoped to provide help for the development of all solid-state lithium batteries and accelerate their commercial application. |
