摘要

We have successfully prepared -Ni(OH)2 flower-like microspheres by the solvothermal method using2-butanone and water mixture solvent for the first time. Then NiO flower-like microspheres wereobtained by annealing the corresponding precursors at 300 C. The flower-like microspheres werecomposed of many nanoplates. The thickness of nanoplates and the dimeter of flower-likemicrospheres were about 20 nm and 6 m, respectively. For comparison, the sole -Ni(OH)2 and NiOnanoplates were prepared in aqueous solution. Experimental results indicated that the as-synthesizedNiO flower-like microspheres kept a relative high capacity retention during charge-discharge process,and their cyclic stability should be improved for potential application in lithium-ion batteries.
