Abstract Lithium metal is considered as the ultimate anode material for high‐energy‐density rechargeable batteries. However, lithium batteries (LMBs) with commercial separators still face some challenges such low cycling efficiency and uncontrollable Li dendrite growth, which seriously hampers commercialization of LMBs. In this study, a novel kind ultrathin (6.2 µm) multifunctional composite separator (TpPa‐SO 3 Li@PE) designed prepared via coating lithiated covalent organic framework nanosheet Li) on surface polyethylene (PE). TpPa‐SO Li@PE integrates features nanochannel arrays abundant immobilized anionic sites, leading to efficient + conduction homogeneous flow. As result, exhibits excellent conductivity (0.96 mS cm −1 ) transference number (0.83) at room temperature, Li/Li symmetric cell using possesses highly stable plating/striping (over 2600 h) high current density (5 mA −2 ). Moreover, Li/LiFePO 4 full cells show performance (high capacity retention 94.9% after 300 cycles 1 C) superior rate specific 113.6 mAh g 5 C).
