摘要
采用不同的制备方法以及控制反应条件制备出不同形貌、尺寸的纳米银,并采用透射电子显微镜对纳米银进行表征。研究结果表明:采用传统溶胶-凝胶法较成熟稳定,制得的纳米银为球形粒子,尺寸均匀,粒径60nm左右。将纳米银与氧化石墨烯(GO)复合后掺杂到磷酸铁锂(LiFePO4)中,制得的LiFePO4-纳米银/GO复合物的首次放电比容量达到158.6mAh/g,具有良好的电化学性能。
Abstract
The silver nanoparticles with different morphologies and size were prepared by using different preparation methods and controlling the reaction conditions,the morphology of silver nanoparticles was characterized by transmission electron microscopy (TEM).The results showed that the traditional sol-gel method was more mature and stable,and the particles prepared were spherical with uniform size and the diameter was about 60nm.The composite of Ag/GO was doped into LiFePO4.The LiFePO4-Ag/GO composite had good electrochemical performance and the first discharge specific capacity was 158.6mAh/g.
