摘要
In this work, we report the synthesis of hierarchical NiCoO_2 nanosheets growing on hollow carbon spheres(denoted as NiCoO_2 NSs@C) via a facile and low-cost process. When evaluated as anode materials for LIBs, the as-prepared hollow NiCoO_2 NSs@C nanospheres are able to exhibit high specific capacity, enhanced cycling stability and good rate capability. A high discharge capacity of 631.7 m Ah g~(-1) is delivered even after 200 cycles at a current density of 400 m A g~(-1), corresponding to approximately 92% of the first reversible discharge capacity. The hierarchical and hollow structures of NiCoO_2 NSs@C nanospheres make a prominent contribution to the excellent lithium storage performance.
