[Sodium-ion Battery Anode: Research Progress on Graphite-based Sodium-ion Battery Anode by the Hong Kong Polytechnic University] Recently, Professor Xu Zhenglong from the Hong Kong Polytechnic University has proposed a novel method to adjust the sodium affinity of graphite by manipulating ether solvents. By introducing sodium metal into the sodium-philic ternary graphite intercalation compound (t-GIC), they have successfully developed a Na/t-GIC anode with high capacity and low operating voltage (0.18 V). This research provides new insights into the sodium-philic chemistry of graphite and offers a potential solution for the preparation of high-energy sodium-ion batteries using cost-effective graphite materials.
