报告人简介

Prof. Xiaolei Wang is currently an associate professor in the Department of Chemical and Materials Engineering at the University of Alberta, and also titled Canada Research Chair in Batteries for Sustainability. He runs his Nano For Advanced Clean Energy (NanoFACE) laboratory and mainly focuses on the rational design, development, and application of novel nanostructured materials for energy-related technologies, including lithium (and other alkaline)-ion batteries, lithium-metal batteries, rechargeable aqueous batteries, metal-air batteries, supercapacitors, and electrocatalytic system for water splitting, CO₂ reduction and fuel cells. Prof. Wang received his Ph.D. at the University of California, Los Angeles, and took the postdoctoral training at the University of Waterloo.

Prof. Wang is the associate editors/young associate editors of several international journals including Energy & Environmental Materials, Renewables, and Frontiers in Chemistry, and editorial board members of Sustainability: Sustainable Chemistry, and Current Trends in Chemical Engineering and Processing Technology. He has so far published over 100 papers in energy and nanotechnology fields including Nat. Commun., Adv. Mater., Energy Environ. Sci., Angew. Chem. Int. Ed., Adv. Energy Mater., etc., and received a h-index of 41. Prof. Wang serves as referees for over 60 international journals and many funding agencies, and is the recipient of Discovery Accelerator Supplement Grant, Petro-Canada Young Investigator Award, and Concordia University Research Chair-Young Scholar. Prof. Wang has organized, chaired or co-chaired on many national (e.g., CCEC, CCCE) and international (e.g., MRS, ECS, EEST) conferences on energy or materials.

报告内容简介

To promote sustainability, we aim to develop cost-effective and reliable alternative battery technologies to LIBs. Aqueous batteries and supercapacitors, particularly zinc-ion devices, offer high safety and promise. Despite challenges like dendritic growth, low Coulombic efficiency, and capacity decay, we use electrode and electrolyte engineering to create low-cost and high-performing Zn-ion batteries and supercapacitors for energy storage and electric vehicles. Recycling and upcycling of batteries, especially LIBs, are also explored to achieve a circular economy. We focus on regenerating or upgrading electrode materials and converting primary batteries into rechargeable ones.
