9月17日下午，受材料学院邀请，澳大利亚卧龙岗大学郭再萍教授在5号教学楼502-1会议室为我校师生作题为“Hybrid Nanostructures as Electrode Materials for Alkali Metal-Ion Batteries”的学术报告。

　　郭再萍教授详细介绍了她的研究团队近几年在二次电池电极材料领域的一些研究进展。首先，受Na₂TiSiO₅材料在钠离子电池中表现出的优异性能启发，郭再萍教授团队成功制备出了新型电极材料Li₂TiSiO_5，并将其用作锂离子电池负极材料，该材料具有优异的结构稳定性，更低的放电电位，能同时保证电池具有更稳定的长循环寿命和更高的放电容量；随后她介绍了如何利用等离子体诱导阳离子深层掺杂TiO₂，可以有效地提高钠离子电池负极材料的储钠性能；除此之外，郭再萍教授团队还探究了电解液锂盐配方对钾离子电池电极界面的影响，以及利用液相剥离的方法制备出超薄Sb₂S₂纳米片结构用以提高钾离子电池的循环稳定性等。报告深入浅出，系统性的研究工作让研究生们受益匪浅。会后，郭再萍教授与参会师生就相关学术问题进行了细致深入的讨论。
