In recent years, with the rapid development of new energy vehicles and flexible direct current transmission projects, and other fields, there was an increasing demand for the metallized film capacitors with high volume ratio and high temperature resistance. Especially under extreme conditions such as high temperature and high electric field, higher requirements were put forward for the electrical performance of dielectric films in capacitors. In this paper, the current research status and development trend of dielectric film materials for metallized film capacitors in recent years were summarized. Firstly, the key factors affecting the energy storage performance of dielectric films were introduced and the failure reasons of metallized film capacitors under operating conditions were analyzed. Secondly, the modification methods of energy storage performance for dielectric films designed on the basis of four aspects, such as molecular chain structure, aggregation state structure, doping of functional fillers, and surface modification were summarized. Finally, the strategies to improve the energy storage performance of dielectric films of metallized film capacitors were summarized and prospected.
