The development of lithium-metal batteries(LMBs)is seriously restricted by the out-of-control dendrites growth and infinite volume expansion.Herein,a pervasive organic-inorganic layer construction strategy is reported for the composite lithium metal anode with congener-derived organic-inorganic solid elec-trolyte interphase(SEI).In this strategy,the organic-inorganic Ag@polydopamine(Ag@PDA)layer is coated on the arbitrary substrates by a simple two-step method.The thin and stable congener-derived SEI is in-situ formed with fewer inorganic components and more organic components during charging/discharging.The polydopamine with sufficient adhesion groups and lithiophilic Ag layer realize near-zero nucleation overpotential during lithium deposition.The low interface resistance and stable lithium deposition are achieved.Moreover,the practical areal and volumetric capacities of the composite anode with three-dimensional copper(3DCu)as the substrate are 10 mAh/cm2 and 1538 mAh/cm3(vs.the mass of anode).The symmetrical cell shows very low polarization voltage(10 mV)and more than 2500 h cycles life at 1 mA/cm2(1 mAh/cm2).The LiNi0.8Co0.1Mn0.1O2(NCM811)-based full cells show improved capacity re-tention(82％)after 100 cycles at 0.5 C.The modified lithiophilic anode with congener-derived interphase provides a promising strategy to realize the next-generation dendrite-free LMBs.
