Abstract

original image

A unique design of a nickel nanocone-arrays 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 0.2C) and excellent cycling capability. They also exhibit an impressive high-rate capability and stable capacities of up to 1700 mAh g−1 at 1C and 1300 mAh g−1 at 2C.
