His scholarly output includes over 170 publications, 21 patents, and an H-index of 61, with more than 13,500 citations. He has received numerous accolades, including the ATSE Solomon Award for Industry–Research Collaboration and the Prime Minister’s Prize for Science as Physical Scientist of the Year. His work exemplifies the integration of fundamental science with industrial application, advancing Australia’s leadership in clean energy technologies.
报告简介：
One of the great global scientific challenges is the availability of energy at low cost, to all. Whilst the ability to generate power from renewable sources, and from a distributed grid, progressed remarkably over the last 15 years, it can only be fully exploited if usage can be decoupled from generation.
Electrochemical energy storage technologies such as batteries and supercapacitors are the primary mechanism to break this link. Developments in the performance of new storage media, whilst maintaining an economical aspect, are crucial for making the use of self-generated renewable energy viable in many more instances. One of the most tantalizing battery chemistries is Lithium-Sulfur (Li-S). With a gravimetric storage potential around 10 times higher than Lithium ion, Li-S batteries are also manufactured from cheap, safe and stable materials, amenable to their widespread deployment. However, Li-S batteries have inherent challenges of stability with cycling, accessing their full storage potential, and obtaining charge-discharge at requisite rates. Many of these inherent challenges are due to slow, or non-selective transport, and porous materials offer the potential to address this behaviour.
In this presentation, recent breakthroughs in addressing these challenges inherent to Li-S will be presented. We have been able to develop Li-S cells with some of the best performances yet reported, and under conditions practical to their wide deployment. This is due to new forms of transport, and the mechanisms behind how porous materials within Li-S cells achieved this, discussed. Building on the knowledge obtained here, we recently expanded this breakthrough to separators used in organic redox flow batteries, and this knowledge will be compared to these earlier discover-ies.
