“…Based on the aforementioned models and discussion, tremendous attention has been drawn toward designing Li host frameworks to regulate and stabilize the LMBs. Carbon matrices, such as graphite felts, carbon nanotubes, graphene, hollow carbon nanospheres, and carbon foams, are among the most researched candidates owing to their easily controlled properties, cost-effectiveness, and easy synthesis and functionalization for real practical applications of LMBs [ 18 , 63–67 ]. In this section, the main principles that must be considered to utilize carbon matrices as Li host materials will be discussed.…”

“…The high mechanical stability and flexibility of a carbon-based framework are essential properties to stabilize the SEI by alleviating volume change, suppressing the Li dendrite growth, and inhibiting the electrode disintegration. These properties make the SEI less susceptible to swelling-related stresses and fluctuations during Li plating/stripping cycles [ 18 , 31 , 33 , 72 , 73 ]. One study, conducted by Zheng et al provided evidence that interconnected amorphous hollow carbon nanospheres, acting as a monolayer coating for Li metal anode, as shown in Figure 4b , help in isolating the deposition of Li metal and facilitating the formation of a stable SEI [ 74 ].…”

Lithium metal batteries have recently gained tremendous attention owing to their high energy capacity compared to other rechargeable batteries. Nevertheless, lithium (Li) dendritic growth causes low Coulombic efficiency, thermal runaway, and safety issues, all of which hinder the practical application of Li metal as an anodic material. In this review, the failure mechanisms of Li metal anode are described according to its infinite volume changes, unstable solid electrolyte interphase, and Li dendritic growth. The fundamental models that describe the Li deposition and dendritic growth, such as the thermodynamic, electrodeposition kinetics, and internal stress models are summarized. From these considerations, porous carbon-based frameworks have emerged as a promising strategy to resolve these issues. Thus, the main principles of utilizing these materials as a Li metal host are discussed. Finally, we also focus on the recent progress on utilizing one-, two-, and three-dimensional carbon-based frameworks and their composites to highlight the future outlook of these materials.

“…The unsatisfactory performance of Li-metal anodes originates from the unstable structural and chemical evolutions at the anode/electrolyte interface, which include infinite volume variation, the formation of unstable solid electrolyte interphases (SEIs) and the growth of Li dendrites. To improve the performance of Li-metal anodes, efforts have been made to regulate the chemical compositions and structures of the electrolyte [1][2][3] and the Li-metal anode [4] to reshape the SEI [5,6] and to rebuild the current collector [4,[7][8][9] . The lithiophilicity of electrolytes at the anode/electrolyte interface was studied as it significantly affects the uniformity of Li deposition/dissolution at the interface.…”

Lithium-metal anodes show significant promise for the construction of high-energy rechargeable batteries due to their high theoretical capacity (3860 mAh g -1 ) and low redox potential (-3.04 V vs. a standard hydrogen electrode). When Li metal is used with conventional liquid and solid electrolytes, the poor lithiophilicity of the electrolyte results in an unfavorable parasitic reaction and uneven distribution of Li + flux at the electrode/electrolyte interface. These issues result in limited cycle life and dendrite problems associated with the Li-metal anode that can lead to rapid performance fade, failure and even safety risks of the battery. The lithiophilicity at the anode/electrolyte interface is important for the stable and safe operation of rechargeable Li-metal batteries. In this review, several factors that affect the lithiophilicity of electrolytes are discussed, including surface energy, roughness and chemical interactions. The existing problems and the strategies for improving the lithiophilicity of different electrolytes are also discussed. This review helps to shed light on the understanding of interfacial chemistry vs. Li metal of various electrolytes and guide interfacial engineering towards the practical realization of high-energy

“…In addition to the stable Li deposition, the empty pores provide space for Li growth, thus moderating the huge volume changes of the Li anode. Accordingly, many studies have focused on Li stabilization using 3D porous structures, including metal foams, [36][37][38] metal meshes, [39,40] porous Cu, [32][33][34]41,42] and porous C. [31,[43][44][45][46][47] These reports demonstrated that the use of 3D porous structures can effectively prevent the growth of Li dendrites, as well as the volume changes of Li, resulting in improved electrochemical performance. However, fine-tuning the structural features such as pore size and thickness, which can determine electrochemical performance, is still challenging.…”

Lithium (Li) metal is considered the best anode material for next‐generation high‐energy density Li‐metal batteries. However, Li dendrite formation and growth hinder the practical applications of Li metal anodes. Herein, we report a three‐dimensional (3D) porous inverse opal nickel structure on a copper foil current collector (Ni IO@Cu) that has a controllable pore size and thickness and is fabricated via colloidal self‐assembly and electrodeposition. The uniform interconnected pores with a large surface area of the Ni IO@Cu structure can effectively dissipate high areal current densities, resulting in the stable formation of a solid electrolyte interface and dense, dendrite‐free, flat lithium deposits. In comparison to the use of bare Cu, the use of the Ni IO@Cu current collector resulted in greatly improved stability and lowered the voltage hysteresis in various Li plating/stripping tests. Moreover, Li‐ion battery and Li‐sulfur battery full cells prepared using the Ni IO@Cu also displayed excellent cycling performance. This work further demonstrates the significance of the 3D porous structure for preparing dendrite‐free Li metal anodes.
