摘      要：In the development of 3D conductive frameworks for lithium metal anode(LMA),two models have been proposed:top growth model and bottom-up growth ***,Li tends to accumulate on the top of these 3D frameworks with homogenous lithiophilicity(top growth)and Li dendrite still *** address this issue,some researchers have focused on developing 3D frameworks with gradient lithio-philicity,which realized bottom-up growth of ***,partial Li nucleation sites on the top of these frameworks were *** by the two models talked above,this work firstly proposed a novel intermittent lithiophilic model for lithium *** demonstrate the feasibility of this model,a bimetallic metal-organic frameworks derived ZnMn_(2)O_(4)-MnO nanoparticles were grown on carbon cloth for *** can cycle stably under ultra-high current and areal capacity(10 mA/cm^(2),10 mAh/cm^(2)).The in-situ optical microscopy(OM)was conducted to observe the Li deposition behavior,no dendrite was found during 80 h in ester-based electrolyte while the pure Li only cycled for *** is more,it can also be well-coupled with LiNi_(0.8)Co_(0.1)Mn_(0.1)O_(2)(NCM811)cathode and solid-state electrolyte,which further prove the advantages of the intermittent model for the development of LMAs with high safety and high energy density.
