Abstract :
Composite anodes based on SnSb alloy and Li2.6Co0.4N compound can provide a reversible capacity more than 650 mAh/g in solid polymer electrolyte. However, the capacity retention on cycling is poor at a high-capacity level. Limited lithium insertion (<500 mAh/g) is favorable for the cyclability. Cyclic voltammetry of the composite electrode exhibits good electrochemical reversibility. Because the nano-sized SiO1.1 host has a relatively small volume change effect and different insertion potential from SnSb and Li2.6Co0.4N, its addition in a small amount into the composite electrode can improve the mechanical and cycling stability.
