摘要：

NiO nanocone arrays were fabricated by a two-step approach for power Li-ion battery applications. Galvanostatic battery tests show that the electrode can deliver a capacity up to 1058 mA h g(-1) after 100 cycles at a low rate of 0.4 C and a capacity higher than 436 mA h g(-1) even at a rate as high as 20 C.
