【摘要】 本文通过选择适量的γ-LiAlO2填充于PEO(聚环氧乙烯)类聚合物电解质,组装了以金属Li为负极、P(EO)20Li(CF3SO2)2N-10Wt%γ-LiAlO2为电解质、基于单质S为复合正极的全固态电池,并研究了其充放电特性。且采用场发射扫描电镜与阻抗图谱分析了容量衰减的可能原因。更多还原

【Abstract】 The composite polymer electrolytes, consisting of a linear poly(ethylene oxide) (PEO), Li(CF3SO2)2N salt, and different amount of у-LiAlO2 as ceramie fillers, were prepared by the solvent casting technique. The all-solid-state Li/S cell was composed of Lithium metal anode, P(EO)20Li(CF3SO2)2N-10wt%у-LiAlO2 electrolyte, and composite sulfur cathode. Electrochemical characterization of Li/S polymer cell are present. The reason of rapid capacity fade rate was study by electron ’microscopy and impedance spectroscopy.更多还原
