Mitigating hydrogen embrittlement in high-strength steels. Hydrogen wreaks havoc in many alloys, leading to embrittlement that can cause catastrophic failure. This is a very serious issue for any industry in which structures are exposed to hydrogen and is a limiting factor for the production, transport, storage and use of hydrogen in a potential hydrogen economy. However, understanding the behaviour of hydrogen in alloys is restricted by the difficulty of observing it. In this project we will ob ....Mitigating hydrogen embrittlement in high-strength steels. Hydrogen wreaks havoc in many alloys, leading to embrittlement that can cause catastrophic failure. This is a very serious issue for any industry in which structures are exposed to hydrogen and is a limiting factor for the production, transport, storage and use of hydrogen in a potential hydrogen economy. However, understanding the behaviour of hydrogen in alloys is restricted by the difficulty of observing it. In this project we will obtain accurate 3D maps showing the position of hydrogen atoms in steel by combining deuteration with cryogenic atom probe microscopy. In this way we will will elucidate how a proposed solution, hydrogen trapping, reduces hydrogen embrittlement, contributing to design criteria for hydrogen-resistant steels.Read moreRead less

Summary
Probing interfacial impedance in all-solid-state lithium-ion batteries. This project aims to investigate the mechanism behind the high impedance at the interface between electrodes and the solid electrolyte in solid-state lithium-ion batteries using advanced in-situ transmission electron microscopy. The outcomes will deepen knowledge in chemical and structural evolution at the electrode–electrolyte interface during battery operation under different conditions, and thus inform the design and fabr ....Probing interfacial impedance in all-solid-state lithium-ion batteries. This project aims to investigate the mechanism behind the high impedance at the interface between electrodes and the solid electrolyte in solid-state lithium-ion batteries using advanced in-situ transmission electron microscopy. The outcomes will deepen knowledge in chemical and structural evolution at the electrode–electrolyte interface during battery operation under different conditions, and thus inform the design and fabrication of safe, high power, and long lasting solid-state batteries for a myriad of portable electronic devices and the emerging electric vehicles.Read moreRead less
Layered and scrolled carbon materials for advancing energy storage systems. This project aims to reveal the structure–property relations in carbon electrodes through the design of model carbon systems that allow the simultaneous control of graphitic interlayer distance, ion diffusion pathway length, and surface functional group density. The project is expected to generate new knowledge on the charging mechanisms of micro-supercapacitors and sodium-ion batteries and technologies for emerging port ....Layered and scrolled carbon materials for advancing energy storage systems. This project aims to reveal the structure–property relations in carbon electrodes through the design of model carbon systems that allow the simultaneous control of graphitic interlayer distance, ion diffusion pathway length, and surface functional group density. The project is expected to generate new knowledge on the charging mechanisms of micro-supercapacitors and sodium-ion batteries and technologies for emerging portable electronics and renewable energy storage applications. The demonstration of high-performance and sustainable energy storage devices is anticipated. This will help to advance the prominence of Australia in the global renewable energy market and the move towards more sustainable economies and lifestyles.Read moreRead less
Microscopy characterisation for the designing of Li-based batteries. This project aims to optimise the design of all-solid-state batteries by employing state-of-the-art microscopy and atomic tomography techniques. Demand for safer rechargeable batteries with higher energy densities has been rapidly increasing.

This project aims to optimise the design of all-solid-state batteries by employing state-of-the-art microscopy and atomic tomography techniques. Demand for safer rechargeable batteries with higher energy densities has been rapidly increasing. The safety issues associated with current lithium batteries become more serious with the size change (small for portable electronics and large for vehicles) because of the difficulty in handling of flammable organic liquid electrolytes. The scientific knowledge and engineering understanding acquired through this project will enable the battery industry to produce higher performance solid state batteries.Read moreRead less

This project aims to investigate and optimise the functional properties of anode-free lithium metal battery electrodes. The project expects to develop a novel, high-throughput electrochemistry platform that can rapidly screen new materials and chemistries across length scales, from single atoms to entire battery cells. Understanding battery performance in such detail is expected to enhance our capability to design and manufacture smart battery materials that are higher performing, safer and longer lasting than current technologies. This should provide significant socio-economic and environmental benefits, through the development of commercially-feasible next-generation devices, used by households or businesses to store renewable energy.Read moreRead less
