Polymer nanocomposite-based dielectric capacitors are promising candidates for high- power-density energy storage devices. However, they exhibit poor performance at high temperatures. A polymer nanocomposite based on sub-nanosheets shows high energy density at elevated temperatures due to the unique structure, geometry, and high surface area to volume ratio of the nanosheets.

用于高温存储的亚纳米填料

基于聚合物纳米复合材料的介电电容器是高功率密度储能设备的有希望的候选者。然而，它们在高温下表现出较差的性能。由于纳米片独特的结构、几何形状和高表面积与体积比，基于亚纳米片的聚合物纳米复合材料在高温下表现出高能量密度。
