  • The past decade has seen increasingly rapid advances in sodium-ion batteries (SIBs), promising alternatives to lithium-ion batteries (LIBs), with advantages of uniformly high natural abundance and cost-effectiveness of sodium resources. The diverse choice of sodium chemistry for positive electrode materials allows aiming at different application scenarios of SIBs according to their energy/power capabilities. Due to their high sodium storage capacity and low working voltage, hard carbon materials are generating considerable interest as negative materials for SIBs. However, there are still some concerns about the poor cycling stability, the low initial coulombic efficiency and insufficient rate capability of hard carbon electrodes. Besides the challenge arising from intrinsic properties of hard carbon, its electrode engineering is another factor that could dramatically alter the overall performance of a composite electrode. The adaptation of hard carbon composite electrodes for different application scenarios is vital to reach the commercialization of SIBs.

    In this context, this research project aims to design sustainable hard carbon electrodes with optimized power and energy performances. This project will research the following aspects: design of bio-based hard carbons to promote the rate capability and initial coulombic efficiency; aqueous processing of active material using bio-sourced and synthetic water-soluble binders to gain a detailed understanding of the interaction between hard carbon and binder.
