摘要： 针对传统电化学教学中知识点孤立、学生难以建立材料制备与性能应用之间的系统性认知，本实验以聚丙烯酰胺(PAM)凝胶电解质的制备及其在柔性水系锌离子电池(FZIBs)中的应用为主线，涵盖从材料合成、物性分析到器件集成与性能评估的全过程，通过以问题为起点、经实验验证、并向实际应用拓展的完整流程，促进理论知识的有机串联与深度整合。本实验以PAM凝胶电解质的制备及其在柔性水系锌离子电池中的应用为核心，包含弯折实验、电导率测定、电池制备、电化学性能评价等过程，旨在培养学生从实验室研究到工程化落地的全局视角。本实验通过融合前沿研究与工程实践，为破解“知识碎片化”教学困境提供了可复制的实践模式，助力新工科人才系统性思维与工程素养的协同发展。

Abstract: This study addresses the limitations of conventional electrochemical education, where knowledge is often fragmented and students struggle to develop a systematic understanding of the relationship between material preparation and performance applications. We present an integrated experiment focusing on the preparation of polyacrylamide (PAM) hydrogel electrolyte and its application in flexible aqueous zinc-ion batteries (FZIBs). The experimental design includes the complete workflow from material synthesis and property characterization to device integration and performance evaluation. Through a problem-driven approach involving experimental verification and practical application extension, students engage in hands-on activities including bending tests, conductivity measurements, battery assembly, and flexible device evaluation. This pedagogical model bridges cutting-edge research with engineering practice, providing a replicable solution to overcome the challenges of fragmented knowledge instruction while fostering the development of systematic thinking and engineering competencies in emerging engineering education.
