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.
