Lithium metal anode (LMA) has attracted much attention as one of the most attractive anode candidates for next-generation high-energy-density batteries because of high theoretical capacity (3860 mAh g-1) and low redox potential (-3.04V vs. SHE) of lithium. However, LMA has the intrinsic issue, continuous solid electrolyte interphase (SEI) formation induced by electrolyte decomposition. Inhomogeneous SEI layers can induce heterogeneous lithium ion diffusion, leading to dendrite formation. In addition, SEI layer is prone to be cracked and reformed with lithium metal deposition/dissolution cycles, which causes critical decays of Coulombic efficiencies and cycling performances. In this study, a heteroatom-rich carbon materials were used as a lithiophilic LMA to guide homogeneous lithium metal growth. In addition, effects of the lithiophilic LMA on the electrochemical performances of lithium metal batteries were studied through several electrochemical analysis methods. |
