Lithiophilic seeds and rigid arrays synergistic induced dendrite-free and stable Li anode towards long-life lithium-oxygen batteries
文献摘要：
High energy density lithium-oxygen battery(LOB)is currently regraded as a promising candidate for next-generation power system.However,the dendrite and instability issues of Li metal anode lead to its poor cyclic stability and low energy density.In this work,lithiophilic Al2O3 seeds induced rigid carbon nanotube arrays(CNTA)/three-dimensional graphene(3DG)is developed as a host material for Li anode,namely Al2O3-CNTA/3DG.It is demonstrated that the lithiophilic feature of Al2O3 seeds and the enhanced rigidity of arrays can synergistically induce the uniform Li flux,inhibit the collapse of arrays,and stabilize electrolyte/electrode interfaces.As a result,the AI2O3-CNTA/3DG-Li anode delivers a high Coulombic effi-ciency above 97％after 140 cycles(8 mAh cm-2 at 4 mA cm-2).With this anode and the breathable CNTA/3DG cathode,the full LOB exhibits a significantly increased life-span up to 160 cycles(500 mAh g-1 at 100 mA g-1),which is almost 3 times longer than that with pure Li foil as the anodes.This work demonstrates a new approach to highly reversibly long-cycling performance of LOBs towards practical application.
