Three-Dimensional Self-assembled Hairball-Like VS₄ as High-Capacity Anodes for Sodium-Ion Batteries.

ABSTRACT: Sodium-ion batteries (SIBs) are considered to be attractive candidates for large-scale energy storage systems because of their rich earth abundance and consistent performance. However, there are still challenges in developing desirable anode materials that can accommodate rapid and stable insertion/extraction of Na⁺ and can exhibit excellent electrochemical performance. Herein, the self-assembled hairball-like VS₄ as anodes of SIBs exhibits high discharge capacity (660 and 589 mAh g^-1 at 1 and 3 A g^-1, respectively) and excellent rate property (about 100% retention at 10 and 20 A g^-1 after 1000 cycles) at room temperature. Moreover, the VS₄ can also exhibit 591 mAh g^-1 at 1 A g^-1 after 600 cycles at 0 °
