摘　　要：介绍了一种有机-无机复合型固态电解质(SPE)的综合化学实验,使学生了解聚环氧乙烷(PEO)的改性策略及SPE在全固态电池中的应用。通过X射线衍射(XRD)表征晶体结构,采用交流阻抗、线性扫描伏安法、恒流充放电等测试增强学生对极化和离子迁移数等概念的理解。该实验有助于学生将化学中的理论知识延伸至实际运用,提高理论水平,锻炼实践能力。A comprehensive chemistry experiment on Organic-Inorganic Composite Solid Electrolytes(SPE)is introduced,aiming to familiarize students with the modification strategies of Polyethylene Oxide(PEO)and the application of SPE in all-solid-state batteries.The experiment involves X-ray diffraction(XRD)characterization of crystal structure,as well as tests such as AC impedance,linear sweep voltammetry,and constant current chargedischarge to enhance students’understanding of concepts such as polarization and ion migration number.This experiment helps students extend theoretical knowledge to practical applications,improves their theoretical level,and enhances their practical skills.
