Ion-exchange membranes and electrodes for redox flow batteries
Grid-scale energy storage for intermittent renewables like solar and wind is an essential element of the transition away from fossil fuel based electricity production. Redox flow batteries have some very interesting characteristics for this stationary storage application:they are safer than other battery typesthe amount of energy stored can typically be scaled up easilythe power and energy of a system are more decoupled compared to lithium and other batteries, making them flexible in their design parameters.Ion exchange membrane and electrode are …

Low cost, long life metal-ion capacitors and supercapacitors for renewable energy storage
Australia boasts rich wind and solar energy resources. To avoid fluctuations placing severe burden on the power grids, a reliable and efficient battery storage is required.The present technology based on lithium-ion batteries suffers from high manufacturing cost, poor safety and short life-span.A new kind of storage devices, metal-ion capacitors (MICs), are expected to overcome the storage and the charging speed of the traditional batteries in the near future, opening new avenues for renewable energy resources. The basic structure of MICs …

Development composite electrode for next generation Li-ion batteries
Australia is rich in lithium battery materials and is poised to be the world leader in sustainable energy storage. The rapid growth in the automobile and energy sector created greater demand for high-performance Li-ion batteries with high energy density. Conventional Li-ion batteries utilise a graphite anode with a limited theoretical capacity. Therefore, we need to develop alternative electrode materials with high energy density and a longer lifespan.Silicon (Si) has received attention owing to its high specific capacity at ambient temperature. …

Safe and non-flammable electrolytes for batteries
Electrolytes play a significant role in determining the performance of energy storage devices. In general, different types of liquid electrolytes have been investigated so far including organic liquids, ionic liquids, and aqueous. Among them, organic liquid electrolytes are highly flammable and volatile, while aqueous electrolytes suffer from a narrow working voltage window. IL liquid showed a promise to circumvent these challenges, however, their practical applications are plagued by the high cost, difficulty in preparation, and toxicity.This project will develop low-cost …

Machine Learning-based pedictive tool for energy storage
The fundamental idea behind the ML approach is to analyze and map the relationships between the physical,chemical, and energy storage properties of materials with their associated output data. This early understanding of the energy storage capabilities through the ML approach helps the material scientists to clearly understand, discover, and optimize the fabrication process to develop highly efficient energy storage systems. It also provides key steps in the device fabrication process omitting excessive experimental stages.

High performance energy storage materials and devices
Energy storage devices, such as supercapacitors, play an increasingly important role in our daily life as a reliable energy supplier. Supercapacitors are a type of energy storage system that possess merits of rapid energy storage and release (high power density) with a cycling lifetime of ten thousand or more. Nevertheless the energy density of conventional electrochemical capacitor is quite low.This project aims to enhance the energy density of supercapacitors without compromising their power density through innovative designing and synthesising electrode …

Is battery storage overrated? Achieving grid equilibrium through digital energy services and analytics
The share of renewable energy in electricity generation has globally increased to 28.3%, however, an acceleration of the sustainable energy transition is required to limit worldwide temperature rise (REN21, 2022).Energy storage offers various benefits, such as balancing the mismatch between electricity supply and demand; however, due to its charge/discharge inefficiencies (energy storage results in a loss of at least 10% of electricity in the charge/discharge process), digital solutions are needed to manage grid equilibrium effectively (Watson et al., 2022).In this …
