摘      要：Contradiction between ultrafast nucleation and deposition rates of lithium(Li)crystals at high rate and heterogeneity of Li^(+)flux resulting from concentration polarization has compromised the performance of Li metal anodes especially at high areal capacity and current ***,multifunctional protective layer consisting of MoO_(3) nanobelt films(MoO_(3)-NF)is introduced on the surface of Li by a simple rolling *** strong binding energy between Li and MoO_(3) guides the homogeneous nucleation and deposition of Li,while the nanobelt networks provide effective ion channels for uniform distribution of the Li+*** of the novel multifunctional protective layer,the MoO_(3)-NF@Li anodes demonstrate a remarkable stability for 800 h with ultralow overpotential of 159 mV at extreme harsh conditions of 60 mA·h/cm^(2) and 60 mA/cm^(2).MoO_(3)-NF@Li||LiNi_(0.6)Co_(0.2)Mn_(0.2)O_(2) full-cells can run 100 cycles with a superior capacity retention of 84.2%under practical test conditions,demonstrating great potential for high output and energy-density metal batteries.
