SEM show that the samples with NH4OH as a chelating agent are uniform,its particles are about 5 m,and tap-density is 2.
探讨了以氨水作为络合剂时产物的形貌特征,扫描电子显微镜(SEM)显示此方法制备产物颗粒均匀,粒径大约5!m,振实密度为2。
Another disadvantage is the low tap-density, which results in a low volumetric specific capacity.
其一是它的电子导电率和离子传导率较低,导致其初始放电比容量较低、倍率性能较差;其二是其Fe~(2+)易被氧化,造成其合成困难,且在合成过程中常采用价格较昂贵的Fe~(2+)化合物为铁源,增加了材料的制备成本;其三是它的振实密度较低,导致其体积比能量较低。
The chemically synthesized CoOOH shows a high conductivity because of its high oxidation state, as well as a high tapping density.
研究结果表明,该方法得到的CoOOH具有更好的导电性能,样品的振实密度有了很大的提高。
