摘要
聚合物基介电电容器因其卓越的电气性能而被广泛应用于电力、军工等领域,但较低的储能密度限制其进一步发展,研究开发具有高放电能量密度的聚合物材料势在必行。评价聚合物材料储能特性的两个重要指标分别是放电能量密度和储能效率,为提高放电能量密度和稳定储能效率,诸多理论与方法被提出与应用。基于材料性能与材料制备手段,介绍了目前国内外关于聚合物材料储能特性复配体系的研究进展,主要围绕全有机复合体系和无机/有机复合体系展开,并指出了目前研究进展的瓶颈。
Polymer-based dielectric capacitors are widely used in the fields of electric and military industry due to the excellent electrical properties. However, the low energy storage density limits the development. Thus, it is imperative to research and develop polymer materials with high discharge energy density. Two important indicators for evaluating the energy storage characteristics are discharge energy density and energy storage efficiency. In order to increase the discharge energy density and stabilize the energy storage efficiency, many theories and methods are proposed and applied. Based on material properties and preparation methods, the current domestic and foreign research progress on energy storage characteristics composite systems are introduced, mainly focusing on all-organic composite systems and inorganic/organic composite systems. The restrictions on the research are discussed.
