Smart Sodium Storage System

closed

The Smart Sodium Storage System project will develop and integrate a new type of sodium-ion battery in a low-cost, modular and expandable energy storage system to be demonstrated at the Illawarra Flame House and Sydney Water’s Bondi Sewage Pumping Station.Key findingsThis project aimed to develop a low cost sodium battery and battery architecture for use in energy storage solutions.The project focussed on material development and identified two candidates for cathodes: layered oxides and Prussian Blue.Hard carbon for the anode dedication made the battery cell construction and demonstration possible.The project also included the development of an Energy Management System and two sodium-ion battery packs produced with oxide based cathode chemistryAlthough the scale-up production technology requires further development, the project helped researchers to build expertise and subsequently take up leadership roles in Australia and overseas.Finally, the project has helped lay the foundation in the field of sodium-ion battery storage for Australia and enabled the University of Wollongong to contribute towards this cutting-edge technology.
