2019年04月15日，应国际实验室陈立桅研究员邀请，加拿大卡尔加里大学Thangadurai教授来纳米所访问交流，并在上午10点整于纳米所A718会议室给大家带来题为“Solid-State Electrolytes for Next Generation Batteries”的学术报告。

报告中，Thangadurai教授首先介绍了目前使用的液态有机电解质存在易燃性差、电化学稳定性差、毒性大等缺点，开发出具有理想物理化学性质的热稳定固体电解质已经迫在眉睫。随后跟大家展示了目前全固态电池的一个研究大背景，涉及到几种无机电解质，包括NASICON, LISICON，钙钛矿和石榴石型材料等，且强调了具有快速离子传导性能的陶瓷材料在全固态锂离子电池领域的重要性。接着提出了对实际固体电解质的关键要求：在流动物质的活性范围内具有高离子和可忽略的电子导电性，以及与高阴极和单质阳极反应时的化学稳定性。后展示了课题组近年来的成果，并且介绍了目前应用于固态锂电池的陶瓷电解质，以及有效的固态电解质和电极方面的设计思路。
