A highly stable Sb based anode material of well-confined Sb@graphene@carbon (Sb@G@C) was developed for high performance PIBs. The Sb@G@C electrode exhibits a reversible capacity of 474 mA h g⁻¹ at 100 mA g⁻¹ (second charge), an outstanding long cycle stability over 800 cycles with a capacity retention as high as 72.3% and an excellent rate performance.
