Lithium metal is the ultimate anode material for next-generation high-energy batteries.Yet,the practical application of lithium metal anodes is limited by the formation of Li dendrites and large volume changes.Herein,an effective multi-dimensional hybrid flexible film (MD-HFF) composed of iodine ion (0 dimen-sion),CNTs (1 dimension) and graphene (2 dimensions) is designed for regulating Li deposition and mit-igating volume changes.The multi-dimensional components serve separate roles:(1) iodine ion enhances the conductivity of the electrode and provides lithiophilic sites,(2) CNTs strengthen interlaminar conduc-tance and mechanical strength,acting as a spring in the layered structure to alleviate volume changes during Li plating and stripping and (3) graphene provides mechanical flexibility and electrical conductiv-ity.The resulting MD-HFF material supports stable Li plating/stripping and high Coulombic efficiency(99％) over 230 cycles at 1 mA cm-2 with a deposition capacity of 1 mAh cm-2.Theoretical calculations indicate that Lil contributes to the lateral growth of Li on the MD-HFF surface,thereby inhibiting the for-mation of Li dendrites.When paired with a typical NCM811 cathode,the assembled MD-HFF‖ NCM811 cell exhibit improved capability and stable cycling performance.This research serves to guide material design in achieving Li anode materials that do not suffer from dendrite formation and volume changes.
