Key Laboratory of Energy Materials and Devices has long been engaged in the research and development of high activity and high energy density energy nanomaterials and the development of matching mass production equipment technology. From the Eleventh Five-Year Plan to the Thirteenth Five-Year Plan, we have devoted ourselves to the design and optimization of anode and cathode materials for lithium-ion batteries by undertaking various national, provincial and municipal research projects. The lab has successfully designed and developed core key materials for lithium-ion batteries such as new nanoanode materials and low-cobalt and cobalt-free cathode materials, as well as supporting materials modification industrialization mass production equipment and process technologies. After years of exploration, our group has made breakthroughs in the research of new nanoanode materials, combining plasma physics and chemical control reactions to successfully synthesize carbon-constrained nanostructures, solving the key problem of capacity decay of lithium-ion batteries. It has broken through the "ceiling" of electrochemical energy storage capacity of traditional electrode materials, and under the current density of 1 C, the specific capacity can be maintained above 800 mAh g^-1, and the cycle performance can be maintained above 500 cycles, and the relevant performance indexes have reached the international advanced level. The mass production equipment has been granted more than 10 patents, providing the basis for the macroscopic preparation of high-density energy storage nanomaterials. In recent years, the scientific research results have been published in international core journals in several academic papers (ACS Nano, 2018, 12, 8037-8047; Mater. Today Energy, 2020, 17, 100439-100447; J. Power Sources, 2020, 459, 228104-228112, etc.). In addition, our group had successfully developed low and no cobalt cathode materials and proposed a simultaneous lithiation strategy to mitigate the capacity and voltage degradation during the lithiation/delithiation progress. An excellent cathode material for lithium-ion batteries had been obtained by this method, it was assembled with a commercial graphite cathode to form a full battery, which had a maximum energy density of 440 Wh kg^-1 at a current density of 0.1 C.
