Solid-State Electrolytes for Next-Generation Energy Storge: Progress, Challenges, and Future Dierctions

Solid-state batteries (SSBs) represent a highly promising solution for the next generation of energy storage systems, offering high energy density, superior safety performance, and a prolonged service life. The development of solid-state electrolyte (SSE) materials is particularly critical, as their high ionic conductivity and interface stability directly determine the overall performance of solid-state batteries. Therefore, we focus on the application of solid-state electrolyte materials in new energy vehicle batteries. This paper adopts the method of literature reading and analytical research to review the cutting-edge progress of various solid-state electrolyte materials in the field of new energy vehicle batteries, revealing their key potential in improving energy density, safety and cycle life. This study concludes that SSEs, including those with carbon nanomaterials, rare earth bromides, and composite structures, significantly enhance the energy density, safety, and cycle life of new energy vehicle batteries. However, further research is needed to address challenges like silicon anode volume expansion and lithium dendrite suppression, while future efforts should focus on high ionic conductivity materials, interface optimization, cost-effective manufacturing, and interdisciplinary collaboration to accelerate solid-state battery commercialization and sustainable development in the new energy vehicle sector.
