Based on a cellulose-derived carbon/graphene framework(CCM/rGO),a lithiummagnesium alloy(LiMg),and a LiF-rich interphase layer, we prepared an ultrathin lithiophilic thickness-controllable lithium metal composite anode CCM/rGO-M-Li.The CCM/rGO provides fast electron pathway and buffer space for volume expansion, while the LiMg sites significantly reduce the lithium nucleation barrier and promote uniform lithium deposition.Meanwhile, the LiF-rich interphase layer further enhances interfacial stability.The symmetric battery based on CCM/rGO-M-Li exhibits excellent cycling stability, with stable cycling for over 1 200 h at 2 mA·cm-2.The full-cell paired with a LiFePO4(LFP) cathode can stably cycle for over 200 times at a 0.5 C rate, with a capacity retention rate of 91.59%.This study provides a new design strategy for constructing lithium metal anodes with ultrathin, lithiophilic, and fluoride-modulated high-performance.
