讲座摘要
Solid-state lithium-metal batteries have the potential to offer improved safety and higher energy density than current lithium-ion batteries. While many studies of solid state batteries focus on the lithium anode, the cathode is equally important and presents many challenges. It is composed of an active material (an intercalation compound), a solid electrolyte and carbon. Practical cells will have to operate under a stack pressure of 1-2 MPa and a few mA cm-2 yet the vast majority of previous studies use high stack pressures, and low current densities, which hides the problems in the composite cathode but at the expense of relevance to practical applications. Here I will discuss the factors that affect the composite cathode is solid state batteries and how to optimise the energy density under conditions relevant to practical cells.
主讲人简介
Dr. Xiangwen Gao is now working as a senior postdoctoral research fellow at the University of Oxford and a Faraday Institution Research Fellow in the SOLBAT project working on investigating various interfaces in solid-state lithium batteries. Xiangwen completed his Materials under the supervision of Prof Sir Peter G. Bruce on Li-O2 batteries at the University of Oxford in 2018. He then worked as a postdoctoral researcher with the 2019 Nobel Chemistry Laureate Prof. John B. Goodenough on Na-ion batteries and solid-state batteries. Xiangwen’s research interest falls into various energy storage systems, including Li-O2 batteries, solid-state batteries, multivalent-ion batteries, etc. He has over 30 peer-reviewed publications on high-impact journals with an H-index of 20, including Nature Materials, Nature Energy, Joule, Advanced Materials, etc.
