表面活性剂对镧锶铁盐形貌和电化学性能的影响
Effect of surfactant on morphology and electrochemical performances of lanthanum strontium iron salts
摘要
Abstract
LaSr3Fe3O10-δ powders were synthesized via hydrothermal method with or without polyethylene glycol (PEG) as surfactant and then sintered at 1000 ℃.The phase structure and microstructure of the samples were characterized by XRD and SEM,respectively.The results show that LaSr3Fe3O10-δ powder with PEG as surfactant has smaller size and less aggregation than those of the powder without the PEG aiding in the sythesis process.The electrochemical performances of LaSr3Fe3O10-δ electrode materials were tested by cyclic voltammetry,AC impedance and galvanostatic charge and discharge.The electrodes using LaSr3Fe3O10-δ powder with PEG in the hydrothemal process display a capacity of 246.0 F · g-1 at a current density of 0.2 A · g-1,higher than that of the electrode material without the PEG aiding in the synthesis.关键词
