▎ 摘 要
In-situ graphene encapsulated surface N-doped MoC nanoparticles (MoC@G-N) are synthesized through arc-discharged method. The MoC@G-N is demonstrated to be a promising anode material for high-rate and long-lifespan LIBs. Consequently, the composite can retain a reversible capacity of 545 mA h g(-1) (1 A g(-1)) and 455 mA h g(-1) (2 A g(-1)) for 300 cycles. Moreover, it can also deliver 545 mA h g(-1) at 10 A g(-1) for 20 cycles and recover to 580 mA h g(-1) after a high-rate measurement for 200 cycles in total. (C) 2019 Elsevier B.V.
