NC@SnO2@Fe2O3 nanorings were successfully designed through a simple method, with uniform distribution of all elements, improved conductivity and stability, and can be used for lithium ion batteries.
High theoretical discharge capacity and environmental benignity of tin oxide and ferric oxide afforded many options for anode materials and attract lots of attention, while wide application was restricted by low electrical conductivity and structural instability of electrode material. To solve such problems, NC@SnO2@Fe2O3 nanor-ings were designed through simple hydrothermal method followed by carbonization of polydopamine. Herein, uniform distribution of all elements guaranteed the synergistic effect and enhanced conductivity, the rigid hollow sandwich structure greatly improved the stability of active substances, which will be conducive for extensive use of LIBs. When evaluated as lithium ion battery anodes, the discharge capacity of 748.2 mAh??g??? 1 of NC@SnO2@Fe2O3 nanorings was obtained at the current density of 400 mA??g??? 1.
