摘      要：For several decades,the promise of implementing of lithium(Li)metal anodes for Li batteries has been aholy grailfor ***,we have proposed a facile design of a MOF-derived Co_(3)O_(4)nanoparticles modified nickel foam,i.e.,Co_(3)O_(4)-NF,as a 3D host to achieve a uniform infusion of the molten *** molten Li was uniformly absorbed on the Co_(3)O_(4)-NF host only in 10 s due to its high Li *** obtained Li-Co_(3)O_(4)-NF composite electrode shows high cycling stability in symmetric cells with low voltage hysteresis even at a high current density of 5 mA/*** full cells of Li-Co_(3)O_(4)-NF/LiFePO_(4)can cycle for more than 500 cycles at 2C without obvious capacity *** after cycling and in situ optical microscope results suggest that the unique 3D host structure of the Li-Co_(3)O_(4)-NF anode plays key roles on suppressing the dendrite growth and decreasing the local current *** believe this work might provide a new strategy for fabricating dendrite-free Li metal anodes and facilitate practical applications in Li batteries.
