Research
General Overview
Since their inception in 1991, lithium-ion batteries have assumed a pivotal role in facilitating a diverse range of applications, extending from cardiac pacemakers to digital cameras and smartphones. While the ubiquity of lithium-ion battery technology is undeniable, the rise of novel applications like electric aviation and electronic textiles has ignited a burgeoning need for alternative battery chemistries and configurations that can deliver enhancements in critical aspects such as energy density, safety, economic viability, lifespan, and charging rate.
How can my research be used to have an immediate, global impact?
I am convinced that the answer lies in developing a battery that can:
1. facilitate the renewable energy transition
2. mitigate the impacts of global climate change
3. enable indigenous sourcing of materials
4. proliferate clean energy manufacturing jobs in North America
All-Solid-State Lithium-Sulfur Batteries
Among various emerging battery technologies, all-solid-state lithium-sulfur batteries have been identified as a promising contender for use in high performance electric vehicles because of their potential for high theoretical energy density, low cost, and improved safety. This research aims to unravel the intricate redox mechanisms underpinning the electrochemical behaviour of all-solid-state lithium-sulfur batteries during operation to identify novel engineering solutions to improve active material utilization, long-term cycling stability, and electrochemical reversibility.
