摘要

应用软化学方法合成层状AgV3O8正极材料,并用XRD(粉末X-射线衍射)、SEM(扫描电子显微镜)和LPSA(激光粒度分析)表征了材料的结构和形貌,采用恒流充放电技术研究了其电化学性能.SEM和LPSA测试结果显示所制备的材料具有较小的颗粒尺寸和较窄的粒度分布区间.恒流充放电测试结果表明,该材料具有高的放电比容量,其中400℃下获得的材料首次放电容量高达760.5 mAh/g.

Abstract

The layered cathode material of AgV3O8 has been prepared for the lithium secondary batteries via the soft chemistry technique. The so-synthesized powders were characterized by XRD(powder X-ray diffraction),SEM(scanning electron microscope) and LPSA(laser particle size analysis).The electrochemical property was investigated by the galvanostatic discharge-charge technique.The results indicated that the particale sizes of AgV3O8 prepared were small in the distribution of narrow range,which leads to high discharge capacity.Among them,the material synthesized at 400 ℃ displayed the first discharge capacity of 760.5 mAh/g.

Key words： soft chemistry synthesis; AgV3O8; cathode material; lithium secondary batteries
