摘要
本研究采用一种可批量化生产的表面改性高介电聚丙烯薄膜制备了一种新型电容器,并对电容器的功率密度、储能特性、容量保持率和大电流下的循环寿命进行了研究。结果表明:采用改性聚丙烯薄膜制作的新型电容器最高储能密度高达3.2 J/cm^(3),且具有优异的综合性能。
A novel film capacitor was prepared by using a mass-produced surface modified high dielectric polypropylene film,and the power density,energy storage properties,capacity retention ratio,and the cycle life under large current of the capacitors were studied.The results show that the maximum energy storage density of the new capacitors with the surface modification polypropylene film can reach to 3.2 J/cm^(3),and the capacitor shows excellent comprehensive performances.
