2015年6月26日上午，材料科学与工程学院“求材”学术论坛在主楼十层小松讲堂举办。论坛由山东大学研究生院、材料液固结构演变与加工教育部重点实验室以及材料科学与工程学院共同主办，材料学院研究生会承办。美国马里兰大学的Wang Chunsheng教授受邀作为本次论坛的主讲嘉宾，作了题为“Enhancing the cycling

stability of liquid electrolyte Li-ion batteries and all-solid-state Li-ion batteries ”的学术报告。本次论坛由白玉俊教授主持，材料学院的教师和研究生们出席了此次学术论坛。

首先白玉俊教授简要介绍了Wang Chunsheng教授的科研经历和主要研究成果。随后，Wang 教授作了题为“Enhancing the cycling stability of liquid electrolyte Li-ion batteries and all-solid-state Li-ion batteries”的学术报告。该报告主要介绍了如何提高液体电解质锂离子电池和全固态锂离子电池的循环稳定性研究。目前限制锂离子电池的高电容量发展的关键是提高其可循环寿命的次数，许多科研人员一直在广泛的致力于提高硅，锡，磷及其复合阳极的循环稳定性，现在最成功的技术之一是使用纳米结构材料。Wang 教授介绍了提高这些高容量电极的循环寿命的不同的策略，总结了高容量硅，锡，磷和SnP3阳极对于提高锂离子和钠离子电池循环稳定性的自我修复机制，并且提出了单一材料全固态锂电池的新概念。Wang 教授的报告思路清晰，讲解到位，将复杂的科学理论深入浅出地讲解，为在座的师生提供了广阔的实验思路及解决问题的方法。

报告结束后，与会的老师与同学纷纷就自己感兴趣的问题向Wang Chunsheng教授提问，Wang 教授给予了详尽的解答。此次论坛加深了同学们对锂离子电池循环稳定性研究的了解，使与会师生受益匪浅。
