Furthermore, the carbon protective layer of HNFs can further enhance the structural stability and improve the conductivity, greatly enhancing ion and electron transport to promote long-term cycle stability. ![]() In addition, the hollow hierarchical structure of HNFs with ultrathin nanosheets accommodates the volume expansion, prevents the pulverization and aggregation issues of composite materials, which can maintain the structural stability during cycling to promote outstanding electrochemical performance. Through Mott-Schottky and EIS tests, it was found that the introduction of a smaller proportion of Ni atoms to form HNFs can produce the optimal electronic structure, increase the electronic conductivity and improve the reaction kinetics. Herein, a series of carbon-based bimetallic Co2-xNixP hollow nanoflowers HNFs) with different amounts of Ni2+ doping were synthesized by simple solvothermal and phosphating process. The rapid development of lithium ion batteries (LIBs) urgently requires anode materials with structural stability and long cycle stability, especially the cycle performance at high current densities. ![]()
