abstract = {Metallic lithium (Li) is regarded as the ultimate anode for
high-energy-density rechargeable batteries due to its
highest theoretical capacity and most electronegative
potential. However, there are serious challenges before
practical application of Li metal batteries (e. g. Li–air
batteries), including the dendritic Li formation and
infinite variation of electrode dimension. Herein, nitrogen
(N) and sulfur (S) co-doping carbon paper (NS-CP) is
synthesized and further modified with a graphite-based layer
(GL) by pencil-drawing. The as-prepared GL modified NS-CP
(GL/NS-CP) is applied to pre-store Li through the
heating-infusion method and Li-GL/NS-CP electrode is
obtained. Experimental and theoretical results have
demonstrated that N, S co-doping can effectively enhance the
lithiophilicity of CP to ensure the uniform Li deposition.
In addition, GL presents excellent Li wettability to rapidly
syphon molten Li. Moreover, abundant pores in GL/NS-CP can
accommodate enough Li to alleviate electrode volume change
and lower local current density to restrain Li dendrites.
Compared with pure Li anode, Li-GL/NS-CP electrode shows
more stable voltage curves with lower overpotential (20
mV for 600 cycles). As a result, Li–air batteries with
Li-GL/NS-CP anodes also exhibit the satisfying cycling life.
These results have shed a new light on the development of Li
anodes.},
