摘要：
The paper reports the fabrication of microscale NiO matrixes with enhanced electrochemical properties through annealing the corresponding chrysanthemum-like alpha-Ni(OH)(2) microspheres. The precursor alpha-Ni(OH)(2) can be synthesized by a hydrothermal method using triethanolamine as the alkaline source. The formation mechanism of chrysanthemum-like alpha-Ni(OH)(2) microspheres is properly discussed. Furthermore, the electrochemical experiments demonstrate that the microscale NiO matrixes show superior electrochemical behavior in lithium-ion batteries due to their unique structures.
