摘要
MXene is one kind of a promising anode material due to its graphene-like structure, excellent electrochemical characteristics and low lithium ion diffusion barrier. But the lower specific capacity couldn’t meet the demands in practical application. Here, we have constructed coconut-derived carbon anchored within the MXene layers, which improves the conductivity to prompt the kinetics upon redox reactions, in the meantime, shorts the transfer distance and buffers volume changes, synergistically improving the electrochemical reversibility during charge and discharge processes. Naturally, the MXene/C hybrid anode delivers a high initial discharge specific capacity of 1951.7 mAh g[Formula: see text] at 0.1 A g[Formula: see text]. Additionally, it maintains a stable cycle with a reversible capacity of 511.7 mAh g[Formula: see text] after 500 cycles at 0.5 A g[Formula: see text]. This work paves a straightforward avenue to developing a versatile MXene-based anode for high performance LIBs.
