摘要
Abstract
Ni-Al layered double hydroxides were prepared with spray technique on the base of chemical co-precipitation. The structure of the product was analyzed and the physical properties were tested. Moreover, it was used as cathode active material to manufacture Zn-Ni cell,and then the charge-discharge performance was studied. The experimental results show that the sample has single α phase crystal structure and irregular particle morphology. Its specific surface area reaches 14.1 m2/g and the average particle size is 18.38 μm. The cell has obviously better cycle stability, higher discharge capacity and voltage plateau than that with spherical β-Ni(OH)2 cathode. The average discharge capacity reaches 287.4 mAh/g within 120 cycles at 1 C rate, and the median discharge voltage attains 1.688 V.关键词
