报告题目:电解液及电极界面建模

报告人:明军 研究员

单位:中国科学院长春应用化学研究所

报告时间:2020年12月22号(星期二)上午9:30-11:30

报告地点:深圳大学沧海校区致腾楼(计算机软件大楼)223会议室

主持人:时玉萌 教授

报告内容简介:电解液作为锂离子电池的主要组成部分,担当着传输Li+离子的重要角色,其重要性如同人类身体的“血液”。但是,如何认知和解析电解液,以及了解电解液在电极材料表面的界面行为,是目前锂离子电池领域内的研究难点。基于此,报告人拟通过:i)提出重新认识固体电解质界面模(solidelectrolyte interphases, SEI)的作用;ii)提出重新认识电解液添加剂的作用;iii)以及提出基于Li+溶剂化结构构筑分子界面模型以解释、预测电极稳定性的三项研究,首次提出金属离子溶剂化结构及溶剂化结构简式对研究电解液配位化学以及理解电极稳定性的重要性。同时,报告人还将对如何设计电解液、如何了解电解液分解过程以及判断电解液稳定性等细节做出自己的见解及分析。
