摘要

In this work, a synergistic strategy of in-situ nitridation by urea pyrolysis and dopamine-derived carbon coating were used to synthesize a micron-sized Ge3N4@C composite, and its electrochemical performance as anode materials for lithium-ion batteries was systematically evaluated. The results showed that the Ge3N4@C composite exhibits higher specific capacity and better cycle stability in the initial cycle. The initial discharge specific capacity reached 1177.81 mAh g− 1 at a current density of 0.1 A g− 1, and the capacity retention ratio after 50 cycles was 40%, which was higher than that of the pure Ge3N4. This study provided a new idea and important theoretical support and technical path for the development of a new generation of high-performance anode materials for lithium-ion batteries.
