摘 要
本研究针对固态电解质在钠离子电池中的应用与性能优化进行了深入探讨。随着新能源技术的不断发展，钠离子电池因其资源丰富、成本低廉等优势备受关注。然而，传统液态电解质存在的安全隐患和性能局限促使研究者转向固态电解质。本研究旨在通过系统分析固态电解质的物化性质及其与钠离子电池性能的关联，揭示其应用潜力并提出优化策略。研究方法包括材料表征、电化学性能测试以及模拟计算等。结果表明，固态电解质显著提升了钠离子电池的热稳定性和循环寿命，同时其高机械强度有效抑制了锂枝晶的形成。此外，通过掺杂改性和界面工程等手段，进一步优化了固态电解质的离子传导性能，降低了界面电阻。

Abstract
In this study, the application and performance optimization of solid electrolyte in sodium ion battery are deeply discussed. With the continuous development of new energy technology, sodium ion battery has attracted much attention due to its advantages such as rich resources and low cost. However, the safety risks and performance limitations of traditional liquid electrolytes have prompted researchers to switch to solid electrolytes. This study aims to systematically analyze the physical and chemical properties of solid electrolytes and their correlation with the performance of sodium-ion batteries, reveal their application potential and propose optimization strategies. The research methods include material characterization, electrochemical performance test, and simulation calculation. The results show that the solid electrolyte significantly improves the thermal stability and cycle life of the sodium ion battery, and its high mechanical strength effectively suppresses the formation of lithium dendrite. In addition, the ion conduction performance of the solid electrolyte is further optimized by means of doping modification and interface engineering.
