Recently, Dr. Wang Gongkai, a teacher at the Institute of New Energy Materials of the Institute of Energy, Materials and Materials Technology, Hebei University of Technology, published his dissertation in the famous journal "Nano Energy" in the field of nano-energy as the first author and author of the correspondence. For the first time, Atomic Layer Deposition Breeding Technology Preparation of lithium titanate / graphene composite electrode materials, and the use of first principles from a theoretical calculation and analysis.
The material's unique microstructure allows it to charge up to 25 seconds to achieve 70% of theoretical capacity (ie, up to 120.8mAh / g at 100C current density). This technology opens up new ideas for the preparation of novel graphene composite electrode materials. The power density of the lithium ion hybrid capacitor with the negative electrode of the composite material even surpasses the double-layer supercapacitor, which has important research significance and practical application value.
