大学化学本科教学中综合化学实验的设计——锂离子电池制作

Production of Lithium Ion Batteries:Design of Comprehensive Chemistry Experiment in College Chemistry Undergraduate Teaching

将CR2032型锂离子电池的制作及电化学性能测试实验设计为大学化学本科生的综合实验并将其应用于本科教学中,建立起基于锂离子电池用正极材料的合成、表征、电极制备及电池组装和性能测试的综合性开放实验。实验以无机材料制备为实验基础,以电化学原理为理论基础,通过文献查阅、确立合成路线、材料制备及表征、锂离子电池制作与测试等多项综合实验内容,使学生了解目前常见的正极材料种类、合成方法、电池的基本结构以及电池性能的测试方法。在教学过程中以学生主动探索为主体,培养学生的科学探究素养,锻炼学生查阅文献、自主设计实验和合作开发的能力。

Production and electrochemical performance test of CR2032 lithium ion battery is designed as a comprehensive experiment for university undergraduate students,which includes the materials synthesis,characterization,electrode preparation,battery assembly and performance testing of cathode materials.Experiments were carried out based on the preparation of inorganic materials and electrochemical principle.Through the literature review,the establishment of synthetic route,material preparation and characterization,battery assembly and testing and other comprehensive experimental methods to enable students to understand the current common cathode material types,synthetic methods,the basic structure and performance test methods of battery.In the teaching process,student exploration is the main body,so that to cultivate students＇ scientific inquiry literacy,access to literature,design experiment and cooperative development capability.
