It may be the solution to energy storage & power conversion in electric vehicles and other high temperature applications. “Ceramics are usually the choice for energy storage dielectrics for high temperature applications, but they are heavy, weight is a consideration and they are often also brittle,” said Prof Qing Wang, Penn State. “Polymers have a low working temperature and so you need to add a cooling system, increasing the volume so system efficiency decreases and so does reliability.”
Dielectrics are materials that do not conduct electricity, but when exposed to an electric field, store electricity...
