Abstract Constructing functional materials on a 3D host is an efficient strategy to tackle issues of lithium (Li) metal anodes. Although non‐Li‐alloying provide structural stability during cycling due reduced lattice distortions, low lithiophilicity and sluggish mass transport kinetics limit their functionality. Herein, synergistic proposed improve intrinsic nucleation sites demonstrate its remarkable efficacy. Two carbon fiber (CF) hosts coated by nanosheets with without oxygen‐enriched filler (OCF) as booster (OCF‐DSC@CF DSC@CF, respectively) are constructed physiochemical properties systematically evaluated reveal the efficacy OCF. By advanced characterization techniques, including tomography location‐dependent electron energy loss spectroscopies, complex heterostructure OCF‐DSC@CF distinctive roles each constituent clearly identified. As verified theoretical electrochemical analyses, incorporation OCF endows substantially improved kinetics. Moreover, induces multifunctional SEI enriched LiF LiC x , which exhibits well‐balanced electrical resistivity ionic conductivity. Benefiting from these attributes, unprecedented cyclability under N/P ratio 1.8, achieving 700 cycles at 0.5C exceptional capacity retention 97.8%.

Lithium metal anodes are ideal for realizing high-energy-density batteries owing to their advantages, namely high capacity and low reduction potentials. However, the utilization of lithium is restricted by detrimental dendrite formation, repeated formation fracturing solid electrolyte interphase (SEI), large volume expansion, resulting in severe "dead lithium" subsequent short circuiting. Currently, researches principally focused on inhibition toward extending maintaining battery lifespans.
