The project aims to develop novel structured phosphorus (Sn/P)-based composites as anode electrodes for sodium ion storage, which have high initial coulombic efficiency (charge capacity), high capacity and stable cycle life. Approaches of modifying surface structure will improve initial coulombic efficiency of Sn/P-based composites, and strategies to stabilise solid electrolyte interphase (SEI) film will obtain long-cycle stability. The success of this project will greatly accelerate the commercialisation of sodium ion batteries and support the utilisation of renewable energy in Australia.

该项目旨在开发新型结构的磷（Sn/P）基复合材料作为钠离子存储的阳极电极，其具有高初始库仑效率（充电容量）、高容量和稳定的循环寿命。表面结构修饰可以提高Sn/P基复合材料的初始库仑效率，而固体电解质界面（SEI）膜的稳定策略可以获得长循环稳定性。该项目的成功将大大加速钠离子电池的商业化，并支持澳大利亚可再生能源的利用。
