Electrochemical Performance of Lithium iron phosphate in aqueous Eletrolyte Solutions Measured by Powder Electrode
利用粉末微电极法对锂离子电池正极材料磷酸铁锂在水溶液中的电化学性能做了分析测试，进行了循环伏安测试，并采用PITT测定出锂离子在磷酸铁锂中的扩散系数随电位的变化规律，用两种模型分析得到的扩散系数的值很相近。结果表明：磷酸铁锂正极材料在水溶液中具有良好的电化学可逆性，循环性能佳。
he electrochemical performance of LiFePO4 in Aqueous Electrolyte Solutions was carried out by using a powder microelectrode. We Studied on Cyclic voltammetry and PITT of LiFePO4 in saturated lithium nitrate solution. The results showed that lithium ion has good electrochemical reversibility during insertion and extraction in aqueous electrolyte solutions.
