Anode materials for advanced sodium-ion batteries (SIBs) require major improvements with regard to their cycling stability, which is a crucial parameter for long-term battery operation. Herein, we report 3R-NbS₂, synthesised by a simple solid-state annealing route, as an anode for SIBs with remarkable cycling stability for 2500 cycles at 0.5 A g⁻¹. The stable nature of the NbS₂ anode was attributed to its dominant capacitive behaviour.

3R-NbS2 作为钠离子电池的高度稳定阳极

先进钠离子电池（SIB）的阳极材料需要在循环稳定性方面进行重大改进，这是电池长期运行的关键参数。在此，我们报道了通过简单的固态退火路线合成的3R-NbS ₂ ，作为SIB的阳极，在0.5 A g ^-1下循环2500次具有显着的循环稳定性。 NbS ₂阳极的稳定性归因于其主要的电容行为。
