Abstract

Due to carbon emission regulations, investing in renewable energy sources and their associated storage technologies, such as batteries, is necessary. The ability of modern commercial lithium-ion batteries to meet the demands for high energy storage, i.e > 350 Wh kg-1 especially for transportation, is now questionable due to limitations of both electrolytes and cathodes. Further, to reach an energy density target of 500-700 Wh kg-1, materials with higher voltage and / or specific capacity are required. This then necessitates the need for future lithium battery technologies which utilize the lithium metal anode such as Lithium- Sulfur (Li-S) batteries.

Through our strategic and commercial projects we are working on both Li-ion and Li-S batteries by applying both new and commercially available materials to enhance energy, power, and safety of the device. Further, we have a range of fabrication equipment that allows us to prototype these technologies for test and evaluation. The optimized combination of the materials (electrode materials, electrolyte, etc.) are selected for investigation and characterization by methods such as SEM, XRD and electrochemical performance tests.

Early Career Researcher
CSIRO – Manufacturing

Marzi is a Chemistry Scientist specialised in lithium batteries. She has completed her PhD on lithium sulfur batteries in 2016 at Swinburne University of Technology in collaboration with CSIRO. After that she joint a commercial project on lithium batteries at CSIRO before starting her current position as Experimental Scientist. She is now working on different aspects of energy storage devices (mainly lithium metal and lithium ion batteries) encompassing electrodes fabrication, electrolytes optimisation, materials characterisation, cell/ battery prototyping. She is also one of the managers of battery prototyping laboratory at Clayton and supervising students (Honours, Masters and PhD) for their research projects on lithium batteries.
