Problems solved by technology

If the working life of electronic components with a general working temperature of 150 ° C is 10 years, then if they work at 300 ° C for a long time, their life will drop sharply to 15 days
Moreover, if the traditional technology using insulating dielectric materials is used to prepare the separator, there will be disadvantages such as poor thermal conductivity and reduced mechanical properties, and due to poor scattering performance, the operating power of the device can only reach 40% of the rated operating power. %, which greatly reduces work efficiency and also causes a great degree of waste of energy
