ARC Future Fellow, Associate Professor Simone Ciampi from Curtin University’s School of Molecular and Life Sciences has found an easy, low-cost method of determining how to produce and retain the highest energy charge in a capacitor. The technology could be of great benefit to all scientists, engineers and start-ups looking to solve the energy storage challenges of the future.

'All electronic devices require an energy source. While a battery needs to be recharged over time, a capacitor can be charged instantaneously because it stores energy by separating charged ions, found in ionic liquids,' says Dr Ciampi.

'There are thousands of types of ionic liquids, a type of 'liquid salt', and until now, it was difficult to know which would be best suited for use in a capacitor. What our team has done is devise a quick and easy test, able to be performed in a basic lab, which can measure both the ability to store charge when a solid electrode touches a given ionic liquid – a simple capacitor – as well as the stability of the device when it’s charged.'

Dr Ciampi says that the study has also been able to unveil a model that can predict which ionic liquid is likely to be the best performing for fast charging and long-lasting energy storage.

Funded by the ARC, the study was led by Curtin University, in collaboration with The Australian National University and Monash University.
