dc.description.abstract应用改进的水热反应法制得粒径小且分布均匀的L iFePO4颗粒,煅烧时加葡萄糖形成包覆碳.XRD、SEM和充放电测试表明,该材料粒径约200 nm,颗粒的尺寸分布比较均匀,具有3.45 V的放电平台,放电容量最高达到140 mAh/g,循环到第40周容量仅衰减2.1%.详细讨论了如何有效调控L iFePO4的粒子尺寸以及包覆碳对其电化学性能的影响.zh_CN
dc.description.abstractLiFePO_(4) was synthesized by means of hydrothermal reaction,in which PVA acts as disperser and glucose as carbon source.The samples were characterized by X-ray diffraction,scanning electron microscopy and electrochemical measurement.SEM results show that the sample is homogeneously composed of grains with a particle size of ca.200nm.In the charge/discharge test,the products exhibited a 3.45V discharge voltage plateau and a maximum specific capacity of 140mAh/g.After 40 cycles,its capacity only declined by 2.1%.Besides these,the mechanism for the influence of the particle size and carbon coating on the electrochemical property of LiFePO_(4)material was discussed in detail.zh_CN
