纳米Bi-Ni氧化物改性碱性MnO2电极
摘要:
采用固相合成法制备了纳米Bi-Ni氧化物,XRD、TEM测试表明,其组成为单斜晶型Bi2O3和菱形晶型NiO的混合氧化物,粒径界于15~45nm之间。通过物理掺杂的方法,用纳米Bi-Ni氧化物对碱性MnO2电极进行改性。掺杂纳米BiNi氧化物,可使MnO2电极的深度放电能力有很大程度的提高,其中,以95mA/g电流密度恒流深度放电,放电容量提高35%左右。

Nanosized Bi-Ni Mixed Oxide Doped Alkaline MnO2 Electrode
Abstract:
Nano-Bi-Ni mixed oxides were prepared by solid-state reaction and characterized by XRD and TEM. The results showed that the oxides consisted of monoclinic Bi2O3 and rhombohedral NiO with particle diameter being in range from 15 to 45 nm. Electrochemical measurements showed that the deep discharge capacity of electrode doped with nano-Bi-Ni mixed oxides at a specific current of 95 mA/g was increased by about 35%.
