We report the synthesis of novel chrysanthemum-like Bi2S3nanostructures as a high-performance anode material for lithium and sodium storage. For lithium ion batteries application, the chrysanthemum-like Bi2S3nanostructures demonstrate high discharge capacity, excellent rate performance and long-term cycling stability. Amazingly, it exhibits superior cycling stability of ∼2% capacity loss after 300 cycles with high capacity of 480 mA g−1remained. The performance is highly improved when compared to the previous reported results of Bi2S3-based materials. Most importantly, the chrysanthemum-like Bi2S3demonstrates good electrochemical properties for sodium ion batteries application. It displays good cycling stability with a stable capacity of 437 mA h g−1over 250 cycles at 0.5 A g−1and excellent high-rate capability. This work will attract more attention to this material, with further improving its performance to speed up its practical use as anode for future Na-ion batteries.
