I will discuss our recent progress on engineering of 2D materials, with a focus on metal ion intercalation and ultra-high temperature treatment (up to 3000-3500K). We developed a nano-battery platform that allows in situ measurement of optical, electrical and structure changes of 2D materials during ion intercalations. We used the nano-battery setup to investigate various properties of 2D materials upon ion intercalation, including Li+, Na+ and K+. Dramatic increases in both transmittance and conductivity were reported, which leads to the highest figure of merit (FOM) for transparent conductor applications. We also extended the knowledge to printed reduced graphene oxide network toward large-scale applications. In a separated topic, I will discuss our effort in the past two years on high temperature material behavior for reduced graphene oxide (RGO) networks. High-temperature stability of RGO networks allows us to uniquely engineer them for a range of emerging applications, such as 3D printed rapid heaters and highly conductive RGO paper as lightweight battery current collectors.

报告内容摘要：

目前动力锂电池面临的两个主要问题是安全性差和能量密度低。固态锂金属电池被认为是解决该问题的最终解决方案，而其走向实用化必须解决固态电解质与电极之间的高界面阻抗的难题。本报告从相关工作的表界面处理中得到启发，提出一种可以显著降低锂金属和石榴石固态电解质之间界面阻抗的方法，并基于该方法成功演示了一种固态锂金属电池的设计。
