The Key Laboratory of Energy Materials and Devices (Liaoning Province) was established in September 2018 to explore key technologies such as nanomaterial macro-preparation, nanostructure control, and electrode high-density energy storage for national major needs in the energy field. Various plasma physical preparation methods such as microwave vapour deposition, hot wire vapour deposition, magnetron sputtering, DC arc and high-energy electron beam are used, combined with chemically controlled modification to complete the design and manufacture of complex structure nanoelectrodes, providing solutions for efficient energy storage and long service life of active materials. The research results provide the theoretical basis and technical support to enhance the engineering application of nano-energy materials and devices.
