摘要： 近年来电动车火灾事故频发，这些事故多与锂离子电池隔膜有关。以“揭秘锂离子电池隔膜”为项目式教学主题，开展大学“高分子结构与性能”课程“高分子凝聚态结构”的教学。学生通过完成明确锂离子电池工作原理、掌握锂离子电池隔膜作用和性能、探究隔膜类型及制备工艺、设计制备和改进电池隔膜等多个项目任务，理解并掌握高分子不同凝聚态结构的特征、高分子结晶的形成与熔融、高分子取向态，并构建成型工艺–凝聚态结构–物理性能之间的联系，设计方案提升电池性能，强化学生团队协作及沟通表达能力，培养其严谨的科学思维、创新意识和学科核心素养。

Abstract: In recent years, electric vehicle fire incidents have been increasingly reported, with many of these accidents being associated with lithium-ion battery separators. This study implemented “Unveiling the Lithium-ion Battery Separator” as a project-based teaching theme for the “Condensed State of Polymers” chapter in the “Polymer Structure and Properties” course. Through completing multiple project tasks, students gained comprehensive understanding of lithium-ion battery operation principles, separator functions and performance characteristics, separator types and manufacturing processes, as well as separator design and performance enhancement. The project facilitated students’ comprehension of various condensed states of polymers, including polymer crystallization formation and melting, polymer orientation, and the interrelationships among processing techniques, condensed states, and physical properties. This teaching approach effectively enhanced students’ teamwork and communication skills while cultivating rigorous scientific thinking, innovation awareness, and core subject competencies.
