It was learned from Xi'an Jiaotong University that the research group of Prof.
Yonghong Cheng from the State Key Laboratory of Electrical Insulation for Power Equipment of the school, by studying the molecular structure characteristics of epoxy resins, the polarization mechanism under the macroscopic electric field, and the influence mechanism of the high temperature energy storage performance, innovatively The asymmetric polyetheramine-alicyclic amine molecular chain structure was designed, and the high temperature resistant flexible epoxy film with the current maximum energy storage density was synthesized.
"Improving the Energy Storage Density of High-Temperature Polymer Film Capacitors" was recently published online in the top international chemical engineering journal "Chemical Engineering"

Organic film capacitors have become an important power energy storage device due to their ultra-fast charging and discharging speed, extremely high power density, high operating voltage, and low loss.
DC conversion and other fields have played an important role

In view of the current situation in this field, the research group of Professor Cheng Yonghong of Xi'an Jiaotong University started from the most common easy-to-process and low-cost dielectric material-epoxy resin, and studied the molecular structure characteristics of epoxy resin, polarization mechanism under macroscopic electric field and high temperature Based on the influence mechanism of the three energy storage properties, an asymmetric polyetheramine-alicyclic amine molecular chain structure was innovatively designed, based on the most widely used bisphenol A epoxy resin in industry
