“…[ 1 ] The Li 3 N, possessing high ionic conductivity (≈10 –3 S cm –1 ), high Young's modulus, and excellent thermodynamic stability, can highly facilitate uniform electrodeposition of Li. [ 30 ] Heterostructure, synergizing the merits of individual components and owning tailored morphologies, attracts considerable interest in recent years. The distinct hetero‐interfaces and strong internal interactions can reconstruct electronic band of materials and spontaneously provide an internal electric field to improve electron/ion transport electrodynamics.…”

Lithium metal batteries are highly desired for durable and high-power energy storage devices due to high theoretical capacity and lowest redox potential. Nevertheless, high activity of Li, large volume change, and Li dendrite formation during cycling severely hinder their further application. Herein, an inventive Cu collector decorated with holey MoO 2 -Mo 3 N 2 heterojunction nanobelts-coated reductive graphene oxide (G-MoO 2 -Mo 3 N 2 , GMM) for highperformance Li metal batteries is reported. The collector features synergistic functions of remarkable lithiophilicity, a built-in electric field formed by splendid interfacial contact, and dense lithiophilic-enriched solid electrolyte interphase layer. They facilitate robust charge transfer and ionic diffusion, and meliorate inhomogenous Li-ion flux for inhibiting the growth of dendrites. In addition, the incorporation of flexible graphene layer enhances the structural integrity and electron transport kinetics. Remarkably, it is demonstrated that GMM significantly enhances Coulombic efficiency of ≈99.5% over 1566 cycles (0.5 mA cm −2 /0.5 mAh cm −2 ). Furthermore, excellent cycling and rate capability of full cells with the GMM@Cu anode and high areal loading of LiFePO 4 cathode (22.2 mg cm −2 ) are also realized. This work illustrates the superiority of synergetic design of lithiophilic sites plus electron transport kinetics for the current collector of Li-metal anode to seek the high energy density.

“…In the first cathodic CV curve, the reduction peaks for N-V 2 O 3 (0.68 V), N-VO 0.9 (0.73 V) and VN (0.72 V) electrodes were observed and then they disappeared in the subsequent cycles, which are ascribed to electrolyte decomposition and formation of the irreversible solid–electrolyte–interphase (SEI) layer. 26,29–31 The weak redox peaks situated at 1.22 V/0.98 V and the low potential (near 0 V) are obviously observed for all electrodes, which are attributed to reversible Li + intercalation/deintercalation. 32–34 In the overlapped subsequent cycles, the gradually stable CV curves reveal prominent chemical reversibility during Li + intercalation/deintercalation.…”

“…candidates for improving Li deposition. [85] As metal nitrides contact Li, metal nitrides and Li will in situ form Li 3 N that was endowed with several unique advantages, including: i) impressive effects on regulating Li + flux distribution; ii) facilitating Li + diffusion through the solid-electrolyte interphase; iii) stabilizing the interface; iv) passivating the active surface of Li metal electrode; and v) reduced elemental metals become the preferred nucleation site for subsequent Li deposition. [86][87][88][89] Two steps generally prepare metal nitrides.…”

“…Furthermore, theoretical calculations showed that Li tends to adsorb on the TiN sheath with a low diffusion barrier, resulting in controllable nucleation position and dendritic-free Li deposition. Other metal nitrides modified carbon substrates have also been reported for LMA, including VN, [85] Co 4 N, [94] Fe 2 N, [87] AlN, [95] Mo 3 N 2 /MoN, [91] Cu 3 N, [89] and Ni 3 N, [96] etc. Generally, metal nitrides are considered the most promising method to ameliorate the lithiophilicity of carbon substrates because of their versatility.…”

The lithium metal anode is a competitive candidate for next‐generation lithium‐ion batteries for its low redox potential and ultra‐high theoretical specific capacity. Nevertheless, obstacles regarding heterogeneous lithium deposition, dendrite growth, and poor Coulombic efficiency limit its practical application. Among rational electrode designs, carbon materials have been regarded as feasible hosts for stabilizing lithium to address the above issues due to their light weight, high conductivity, and adjustable physicochemical properties. Therefore, tremendous efforts have been made to design stereoscopic carbon materials with multitudinous lithiophilic sites and large specific surface areas to facilitate rapid lithium‐ion flux, nucleation and mitigate lithium dendrite formation by controlling the kinetics of lithium deposition. Furthermore, the mechanism of lithium plating/stripping is commendably elucidated with the help of advanced in situ characterization techniques. This progress report systematically reviews progress in carbon materials/lithium composite anodes for lithium metal batteries and the detailed parts are as follows: 1) carbon/lithium composite methods; 2) design lithiophilic mechanism; 3) various carbon materials substrates; 4) advanced in situ characterization techniques for lithium metal anodes; and 5) prospects toward the practical applications of advanced lithium metal batteries. This review provides new insights into lithium metal batteries’ technological development and practical application.
