摘要
Abstract The highest theoretical capacity and lowest redox potential of lithium metal make lithium‐based batteries the “holy grail” of the next‐generation batteries. However, the uncontrollable dendrite growth and infinite volume change of lithium seriously hinder the real‐world implementation of lithium‐based batteries. Herein, a flexible MXene@iodine‐doped red phosphorus (MXene@RP) paper with iodine‐doped red phosphorous particles evenly distributed on the surface and interlayer of MXene matrix is designed by a simple vapor condensation reduction approach. The MXene@RP paper can be used as an efficient matrix to enable dendrite‐free lithium deposition. On the one hand, the iodine doping alleviates the low conductivity shortcoming of red phosphorus, making it facilitate homogeneous lithium nucleation, thus promoting uniform lithium deposition and suppressing dendrite growth. On the other hand, the unique layered structure of conductive MXene paper provides ion transport channels and free spaces for lithium loading, alleviating the volume change induced structural damage. As a result, the MXene@RP paper with preloaded lithium exhibits long‐term cycling stability. Particularly, a full cell based on Li‐MXene@RP anode can maintain 81.4% of the initial capacity after 600 cycles at 4 C. The MXene@RP‐based anode increases the potential applications of MXene and provides a guide for the design of dendrite‐free lithium hosts.
