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.

固定式可充电钠、钾离子电池用硬碳负极材料的研制仍然是一个重大的技术挑战。该项目旨在利用两种截然不同的生物质原料来源，高粱和夏威夷果壳农业废料来制造低成本、高性能的碳阳极。目前的碳阳极材料，如石墨或碳化蔗糖、沥青或酚醛，都存在性能差、成本高、碳产量低和设备耐用性等问题。该项目将研究生物质前驱体、定制石墨烯和碳合金的组合，以显着提高阳极性能，同时最大限度地降低成本。
