摘要
【目的】聚焦新型α-MoO_(3)/CuO复合材料,深入探究其电化学性能与结构特性。【方法】通过水热合成法制备材料,运用多种测试手段进行表征。【结果】结果显示,该复合材料在比电容上达到3.8 F·g^(-1),是α-MoO_(3)材料(1.8 F·g^(-1))的2.11倍;导电性能优异,在高频条件下离子导电性显著;充放电性能良好,在不同电流密度下电容量均高于α-MoO_(3)。通过SEM、EDS和XRD等手段,证实了其成分与形貌特征,CuO颗粒均匀分布于α-MoO_(3)表面,保持了结构的稳定性。【结论】研究结果可为锂离子电池电极材料的优化提供参考。
[Purposes]This study focuses on a novelα-MoO_(3)/CuO composite to investigate its electro⁃chemical properties and structural characteristics.[Methods]The material was synthesized via a hydro⁃thermal method and characterized using multiple analytical techniques.[Findings]The results demon⁃strate that the composite exhibits a specific capacitance of 3.8 F·g^(-1),which is 2.11 times higher than that of pureα-MoO_(3)(1.8 F·g^(-1)).The material shows excellent conductivity,particularly significant ionic con⁃ductivity under high-frequency conditions,along with superior charge/discharge performance,maintain⁃ing higher capacitance thanα-MoO_(3)at various current densities.Structural analyses(SEM,EDS,and XRD)confirm the homogeneous distribution of CuO particles on theα-MoO_(3)surface while maintaining structural stability.[Conclusions]These findings provide valuable insights for optimizing lithium-ion battery electrode materials.
