Description

technical field [0001] The invention relates to the technical field of electronic materials, in particular to a method for manufacturing thin film composite materials. Background technique [0002] With climate change and the continuous reduction of fossil fuels, human beings are turning their attention to new sustainable energy sources. Among them, the development of solar energy and wind energy has become a focus, which has also promoted the development of electric vehicles and hybrid electric vehicles. [0003] In these electric transportation, energy storage devices are particularly important. Electrochemical capacitor is an energy storage device between traditional capacitors and batteries. It has attracted people's attention due to its high power density, high energy density, long cycle life, and short charge and discharge time. The electrode material is the most critical part and the main factor determining its performance. Therefore, the development of electrode mat...
