A robust interphase via in-situ pre-reconfiguring lithium anode surface for long-term lithium-oxygen batteries
文献摘要:
Lithium-oxygen(Li-O2)battery is considered as one of the most promising alternatives because of its ultrahigh theoretical energy density.However,their cycling stability is severely restricted by the uncon-trollable dendrite growth and serious oxygen corrosion issue on Li surface.Herein,a sulfur-modified Li surface can be successfully constructed via chemical reaction of guanylthiourea(GTU)molecule on Li,which can induce the selectively fast decomposition of lithium bis(trifluoromethanesulfonyl)imide(LiTFSI)to form a smooth and stable inorganics-rich solid-electrolyte interphase(IR-SEI)during the sub-sequent electrochemical process.Such an IR-SEI cannot only offer a highly reversible and stable Li plat-ing/stripping chemistry with dendrite-free property(10 mA cm-2-10 mAh cm-2,>0.5 years;3 mA cm-2-3 mAh cm-2,>1 year)but also endows the Li metal an anti-oxygen corrosion function,thereby signifi-cantly improving the cycling stability of Li-O2 batteries.This work provides a new idea for constructing functional solid-electrolyte interphase(SEI)to achieve highly stable Li metal anode.
