摘要：

The aligned freestanding nanorods (NR) of Co(3)O(4) and nanoporous hollow spheres (NHS) of SnO(2) and Mn(2)O(3) were investigated as the anodes for Li-ion rechargeable batteries. The Co(3)O(4) nanorods demonstrated 1433 mAh/g of reversible capacity initially and then decreased gradually. The NHS of SnO(2), and Mn(2)O(3) delivered enemy densities as 400 and 250 mAh/g, respectively, in multiple galvonastatic discharge-charge cycles. The morphologic changes of the nanostructure anodes were investigated. It was found that Co(3)O(4) NR broke down during cycles, but SnO(2) NHS still maintained their structural integrity in multiple cycles resulting in sustainable high capacity. The nanostructured metal oxides exhibit great potential as the new anode materials for Li-ion rechargeable batteries with high energy density, low cost, and inherent safety.
