基于虚拟仿真实验的锂离子电池正极材料制备及性能探究

Virtual Simulation Experiment on Preparation and Performance of Cathode Materials for Lithium Ion Batteries

随着我国新能源行业的迅猛发展,不少高校开设了锂离子电池材料的制备、表征、电池组装和性能测试等综合实验,取得了很好的教学效果。但是由于设备成本和教学时间的限制,无法满足全部实验需求。我们采用虚拟仿真技术,通过虚拟实验过程中正极材料的制备、锂离子电池的组装和性能测试的完整流程,让学生熟悉电化学实验的基本操作技能和相关仪器的使用方法,进而在实际操作中提高实验效率和成功率,建立了虚实结合、线上线下融合的教学模式,拓宽了学生的视野,培养了学生的动手能力和创新意识。

With the rapid development of new energy industry,many universities have launched comprehensive experiments about preparation,characterization,battery assembly and performance testing of lithium-ion battery materials,and have achieved good teaching results.However,due to the limitations of equipment cost and experimental time,it is impossible to meet all experimental needs.We use virtual simulation technology to make students familiar with the basic operation skills of electrochemical experiments and the use of related instruments.Through the virtual experiment about the complete process of lithium-ion batteries including preparation of positive electrode materials,assembly of and performance testing during,we established a new teaching model of online and offline integration and improved the experiment efficiency and success rate in actual operation.At the same time,this model broaden students’vision and cultivate students’practical ability and innovative awareness.
