The development of hard carbon anode materials for stationary rechargeable sodium and potassium ion batteries remains a major technological challenge. This project aims to utilise two very different biomass feedstock sources, sorghum and macadamia shell agricultural waste to manufacture low-cost, high-performance carbon anodes. Current carbon anode materials such as graphite or carbonised sucrose, pitch or phenolics suffer from poor performance, high cost and/or low carbon yield and device durability issues. This project will investigate combinations of biomass precursors, tailored graphene and carbon alloys in order to significantly enhance anode performance while minimising cost.Read moreRead less

This Project investigates a new paradigm for chemicals production, moving away from large-scale centralised plant to distributed manufacture in relatively small localised facilities. The Project is built on the conjunction of a revolutionary process systems synthesis methodology with a new approach to highly compact equipment manufacture. The Project is of great significance to developing countries and to smaller, remote economies such as Australia's, which cannot justify or compete with world-scale production facilities. We will develop our ideas in a case study and identify routes to practical implementation of this example in particular and of the new approach in general.Read moreRead less

This project aims to understand the reactions taking place on the major gangue (waste) mineral during the recovery of base-metal and precious minerals. The mining industry is processing low grade complex ores and experiencing difficulties in rejecting gangue minerals in mineral separation and metal extraction plants. The project will develop new technologies that manipulate these reactions to achieve mineral separation and metal extraction efficiently and economically. These technologies may provide value in processing low quality complex polymetallic resources using low quality water, whilst halving the operating costs of mineral concentrators and providing corresponding reductions in harmful emissions.Read moreRead less
