摘要

Lithium metal anode(LMA)is the ultimate"Holy Grail"electrode for next generation high-energy-density batteries.Nevertheless,its instinct high reactivity is a formidable challenge and has intensified side reactions,destabilized the electrode/electrolyte interface and restricted the operating conditions strictly,thus hampering its practical application.Here,we"make up"the Li metal(M-Li)by constructing vaselinecoated layer by a simple dip-coating or casting method.With the chemically stable and hydrophobic vaseline protective layer,the stability of Li towards humid and corrosive atmosphere has been greatly improved.The M-Li guaranteed stable and prolonged cycling life after the anode suffering from corrosion in moist air(relative humidity-65%)or corrosive electrolyte(with 10,000 ppm H2O or S)both in symmetric cells and LiFePO4 full cells.This work illustrates a convenient,economic,and industrial applicable method for stable LMA.
