You are invited to a SafeREnergy Seminar
Date: Tuesday 31st October
Time: 12noon – 1pm (AEDST)
To achieve a net-zero emission target in 2050, there is an urgent need to reduce the consumption of fossil fuels for electricity generation and transportation. The growing demand for electricity generation from renewable energy sources requires highly efficient energy storage systems to resolve the distribution and intermittent issues. Transition to road electrification is also underway with electric vehicles (EV) being produced on an increased scale annually. Advanced energy storage systems based on rechargeable batteries are considered as the core technologies for electric vehicles and renewable energy industry.
Owing to the superior high energy density, metal air batteries (e.g. lithium–oxygen batteries, sodium–oxygen batteries) have been considered promising advanced battery systems to meet today’s stringent requirements as the power source for electric vehicles (EVs). However, the development of metal air batteries is still constrained by several serious challenges, including uncontrolled side reactions, low energy efficiency and poor cycling life. The electrochemical performances of lithium–oxygen batteries await dramatic improvement in the design of porous oxygen cathodes, efficient electrocatalysts and stable metal anodes.
In this talk, Dr Bing Sun will present the research outcomes from his group on materials innovation for rechargeable metal air batteries. First, the family of metal air batteries will be introduced. Second, the design of porous carbon-based materials and redox mediators for high-performance air (oxygen) cathodes will be discussed. Third, facile and effective methods to enhance the electrochemical performance of lithium/sodium metal anodes will be presented, including electrolyte optimization, three-dimensional current collector design, and dual interface engineering on lithium/sodium metal anodes.
Dr Bing Sun is a senior lecturer in School of Mathematical and Physical Sciences at University of Technology Sydney (UTS). He completed his Ph.D. at UTS in 2012 and then started his postdoctoral research in the Centre for Clean Energy Technology at UTS. His research interests focus on the development of next-generation battery materials and technology for high-energy-density batteries. He is the recipient of Australian Research Council (ARC) Discovery Early Career Researcher Award (2018) and ARC Future Fellowship (2022). Dr Sun has published more than 110 peer-reviewed articles, including Nat. Energy., Nat. Commun., Sci. Adv., Adv. Mater., JACS, and Angew Chem. His research outputs have attracted 9,200 citations with an h-index of 57 (Web of Science).
