Their landmark research established that inexpensive and high-performance batteries are achievable. In comparison to lithium-ion batteries, these batteries use commonplace and inexpensive sodium salts.

The team used molecular simulations and experimental design. They demonstrated a battery with a sodium metal anode and safe, high performing ionic liquid electrolytes.

Industry partner involvement in prototyping spurred further initiatives in next-generation energy storage. This resulted in tested cell prototypes with lithium or sodium combinations.

The project’s discoveries have attracted other potential industry partners. There are opportunities for the technology to be integrated into electric vehicles and in the home. These batteries could be powering households and industries worldwide in the future.

Research partners in both countries have deepened scientific collaboration. Researchers conducted regular:

• video networking
• face-to-face meetings
• project team workshops
• reciprocal research

Throughout this project, energy materials researchers received training that has strengthened India-Australia collaborations. Involving PhD students in the project has deepened the ranks of the next generation of researchers.

The research results are published in high-impact journals. The team also presented their research at several conferences worldwide.

The AISRF-funded research paves the way for novel lithium and sodium energy storage applications.

Overall the project addressed an issue of significant importance to both countries. The project demonstrated how enduring economic, environmental and social benefits is possible with enhanced battery technologies.

There are plans for upscaling the prototyping facilities into a pilot facility. There is an intention to develop a start-up to utilise and build on some of the AISRF outcomes.
