储能聚合物复合方式的研究进展

Study of polymer and inorganic compounding methods for energy storage

新能源动力、医疗仪器、地下勘探、高功率脉冲等行业的高速发展对介质电容器的要求越来越高。聚合物基薄膜电容器的高功率密度、高击穿场强、高可靠性、低损耗、小体积等优点备受关注。但由于聚合物本身低介电常数的特点导致了其能量密度较低,限制了其在高端领域的应用。而聚合物通过不同方式与其他有机或无机物的复合都是提升能量密度的有效途径。介绍了聚合物基薄膜电容器与无机物的复合方式研究现状,分析了不同复合方式的优势与不足,并讨论了未来聚合物基薄膜电容器的发展前景。

The high speed development of industries such as new energy power,medical instruments,underground exploration,and high power pulses are demanding more and more dielectric capacitors.Polymer-based film capacitors are attracting attention for their high power density,high breakdown field strength,high reliability,low loss,and small size.However,the low energy density due to the low dielectric constant of the polymer itself has limited its application in high-end fields.And polymer is an effective way to enhance the energy density by compounding with other organic or inorganic materials in different ways.This paper introduces the current research status of polymer-based film capacitors compounded with inorganic materials,analyzes the advantages and shortcomings of different compounding methods,and discusses the future development prospects of polymer-based film capacitors.
