Abstract

We have developed hierarchical double-shelled SnO₂ hollow spheres by a sequential template-engaged method, in which the loosened SnO ₂ floccules are well-grown on the inside wall of the hollow spheres. The unique hierarchical structure could provide more active sites for Li-Sn alloying-dealloying reaction and fast insertion/extraction of Li⁺ ion with superb conductivity, helping to store more lithium (2578 mA h g ^-1) with great cycling stability.
