Metallic lithium anode is widely applied to building highenergy-density batteries such as lithium–sulfur and lithium–oxygen batteries because of its high specific capacity(3860 mAh g?1)and lowest negative potential(?3.04 V *** hydrogen electrode(SHE))[1,2].However,the practical applications of Li anode remain challenging[3–6].The large volume change during repeated plating/stripping of Li would cause mechanical and interfacial instability[7,8].The solid electrolyte interphase(SEI)layers on lithium surface with poor elasticity are vulnerable to crack under variable stress/strain,leading to continuous side reactions between exposed fresh Li and electrolyte[9–11].In addition,the uncontrollable nucleation and growth of Li incur the formation of dendrites,which could accelerate detrimental parasitic *** of the uneven stripping,dendritic Li may deteriorate into electrically disconnected or“dead”Li,resulting in poor Coulombic efficiency,rapid capacity decay,and short circuit risk[12–17].
