纳米NiO负极材料的制备及电化学性能
Synthesis and electrochemical performance of nano-sized NiO anode material
摘要
Abstract
Ni(OH)2 precursors were prepared by latex-precipitation method and direct-precipitation method,respectively, then calcinated at 500 X, for 2 h to obtain NiO.The structure, morphology and performance of NiO were characterized by XRD,SEM, charge-discharge and AC impedance tests, the lithium insertion-extraction behavior was studied. Nano-scale NiO material obtained by latex-precipitation method was uniform and smaller in size. When cycled in 0.01 -3.00 V with the current of 100 mA/g,the specific charge capacities in the 30th cycle of material prepared by latex-precipitation method and direct-precipitation method were 427.3 mAh/g and 325.0 mAh/g, respectively, the capacity retention rates were 76.9 % and 39.9 %, respectively.关键词
