“一流学科”建设中元素化学课堂教学内容的设计--以碱金属元素为例谈元素结构与性质及其在锂离子电池中的应用

Design of Classroom Teaching in Inorganic Chemistry:Structure and Properties of Alkali Metal Elements and Their Applications in Lithium-Ion Batteries

以“碱金属的结构与性能及其在锂离子电池中的应用”为例说明元素化学课堂教学中的方法,旨在引导学生学习与掌握碱金属的结构与性质的基础知识,使学生对碱金属元素在锂离子电池中应用产生兴趣,领悟无机化学相关的科学前沿的新知识、新规律和新概念,培养学生的创新意识。同时,分组讨论碱金属的结构与化学性质之间关系及其在新能源领域中的应用,组织学生深入到开展相关研究的课题组,在教师指导下开展锂离子电池电极材料制备与表征以及器件组装和电化学性能测试,并根据获得的结果复习课堂中讲授的知识。进一步,鼓励和推进学生开展碱金属在新能源器件中应用的本科生科研训练,在科学研究中应用无机化学基础知识,实现课本知识与科学实践相衔接。

This paper uses“the structure and properties of alkali metal elements as well as their applications in lithium-ion battery”to illustrate the concrete methods in the classroom teaching of elementary chemistry.It is aimed at guiding the students to understand the structure and properties of alkali metal elements and arising their interest in applications of alkali metal elements in lithium-ion battery in the classroom land discussion.The relationships among the structure,chemical performance and applications in lithium-ion battery for alkali metal elements have been discussed in detail.Furthermore,a series of experiments including synthesis and characterization of electrode materials,and fabrication and measurement of devices,will be executed.Finally,the students have also been encouraged to execute“Students Research Training Program,SRTP”in new energy materials related institutes,and in this way the classroom knowledge and scientific research have been linked closely.
