With its high theoretical capacity, lithium (Li) metal is recognized as the most potential anode for realizing a high-performance energy storage system. A series of questions (severe safety hazard, low Coulombic efficiency, short lifetime, etc.) induced by uncontrollable dendrites growth, unstable solid electrolyte interface layer, and large volume change, make practical application of Li-metal anodes still a threshold. Due to their highly appealing properties, carbon-based materials as hosts to composite with Li metal have been passionately investigated for improving the performance of Li-metal batteries. This review displays an overview of the critical role of carbon-based hosts for improving the comprehensive performance of Li-metal anodes. Based on correlated mainstream models, the main failure mechanism of Li-metal anodes is introduced. The advantages and strategies of carbon-based hosts to address the corresponding challenges are generalized. The unique function, existing limitation, and recent research progress of key carbon-based host materials for Li-metal anodes are reviewed. Finally, a conclusion and an outlook for future research of carbon-based hosts are presented. This review is dedicated to summarizing the advances of carbon-based materials hosts in recent years and providing a reference for the further development of carbonbased hosts for advanced Li-metal anodes.

“…In addition, the conformal Li 2 O coating produced in situ on lithiated NiCo 2 O 4 nanorods provided a high effective surface area and surface lithiophilicity, thereby enabling stable Li plating/stripping without Li dendrite growth even at a high current density of 5 mA cm −2 . [49] Similar approaches have exploited the synergistic effects between the macroporous metal host and lithiophilic nanomaterials such as Cu nanowires, [50] Cu 2 O nanowires, [51] CuO nanoflowers, [52] V 2 O 5 nanobelt arrays, [53] and ZnO nanosheets. [54] In particular, Cu 2 O nanowires on 3D Cu foam exhibited stable cycling behavior for >500 cycles with overpotentials as low as 10 mV (Figure 2b).…”

In view of their high energy densities, absence of memory effects, and high round-trip energy efficiencies, conventional lithium-ion batteries (LIBs) are widely used on scales ranging from compact electronic devices to grid systems [8,9] but are currently reaching their maximal capacity, as their specific/volumetric energy densities are limited by the use of heavy metal-based active host materials. [10,11] The use of Li as a high-energy active anode material is a possible solution to this problem, as this metal exhibits a high theoretical capacity of ≈3860 mAh g −1 and a low redox potential (−3.040 V vs the standard hydrogen electrode). [12,13] However, the Li-metal anode (LMA) has some fatal drawbacks originating from highaspect-ratio metal growth, e.g., continuous electrolyte consumption, Coulombic efficiency (CE) reduction, elevated cell polarization due to side reactions producing dead Li, and safety issues caused by electrode short-circuiting. [14,15] Recently, these drawbacks have been addressed by several approaches such as electrode design and electrolyte engineering. [16-21] Metal growth can be described by a first-order linear equation as Although the lithium-metal anode (LMA) can deliver a high theoretical capacity of ≈3860 mAh g −1 at a low redox potential of −3.040 V (vs the standard hydrogen electrode), its application in rechargeable batteries is hindered by the poor Coulombic efficiency and safety issues caused by dendritic metal growth. Consequently, careful electrode design, electrolyte engineering, solid-electrolyte interface control, protective layer introduction, and other strategies are suggested as possible solutions. In particular, one should note the great potential of 3D-structured electrode materials, which feature high active specific surface areas and stereoscopic structures with multitudinous lithiophilic sites and can therefore facilitate rapid Li-ion flux and metal nucleation as well as mitigate Li dendrite formation through the kinetic control of metal deposition even at high local current densities. This progress report reviews the design of 3D-structured electrode materials for LMA according to their categories, namely 1) metal-based materials, 2) carbon-based materials, and 3) their hybrids, and allows the results obtained under different experimental conditions to be seen at a single glance, thus being helpful for researchers working in related fields.

“…Several metal compounds, such as ZnO, CoO, Co 3 O 4 , CuO, Cu 2 O, V 2 O 5 , and Ni 3 N, also present the similar effect as the above metal materials. [25][26][27][28][29][30] In addition, some typical polar functional groups, such as pyrrole, pyridine, and S-, O-, N-containing functional groups were also used to improve the lithiophilicity of 3D Li metal anodes. [31][32][33][34][35][36] These lithiophilic materials will be introduced in detail as follows in combination with the fabrication methods or structures.…”

Lithium metal batteries (LMBs) are considered promising candidates for the next‐generation rechargeable batteries due to the ultrahigh theoretical specific capacity (3860 mAh g−1) and the lowest negative electrochemical potential (−3.040 V versus the standard hydrogen anode) of lithium metal. However, the practical application of LMBs has been hindered by various serious challenges, especially the low cycling stability of lithium anodes due to the uncontrolled growth of lithium dendrites, unstable solid–electrolyte interphase, and excessive volume change of lithium metal. 3D lithium metal anodes with reduced local current density and alleviated volume expansion can be used to improve the safety performance of LMBs. The design of various 3D structures is therefore critical to achieve high‐performance lithium metal anodes. This review summarizes recent advances of several important 3D porous structures such as foam structures, parallel arrays, interweaved structures, coiled structures, Janus structures, gradient structures, and alloy frameworks for stable and dendrite‐free lithium metal anodes. The constructing strategies and modification methods of 3D lithium metal anodes are discussed in detail. The design and construction of novel 3D porous current collectors are expected to provide promising opportunities for the next‐generation of high‐energy‐density LMBs.
