摘要：

A unique design of a nickel nanocone-array supported silicon anode is introduced for high-power and long-life lithium-ion batteries. The nanostructured Si anodes show a high reversible capacity of around 2400 mAh g(-1) (at 0.2 C) and excellent cycling capability. They also exhibit an impressive high-rate capability and stable capacities of up to 1700 mAh g(-1) at 1 C and 1300 mAh g(-1) at 2 C.
