“…Although the plating of metallic Na on carbon‐based hosts, as well as that for metallic Li/K, generally starts with a voltage dip below 0 V, [ 29,49,51 ] the possible existence of quasi‐metallic Na clusters after the sodiation of HC at 0.02–0.00 V was proposed based on the results of various analyses. The atomic pair distribution function (PDF) and differential pair distribution function (d‐PDF) analysis at different discharge states (Figure 3f) revealed distracted interlayer spacing from 0.1 to 0.03 V which may be derived from the insertion of Na + into the graphitic sheets, and the curves from 0.03 to 0.01 V presented few signs that they may be derived from Na clusters.…”

scarce resources, uneven distribution, and arduous recycling of lithium. Sodium-ion batteries (SIBs) and potassium-ion batteries (PIBs) operating with similar mechanism to that of LIBs are considered as affordable alternatives, [2] as a result of the desirable performances as well as much abundant resources of sodium and potassium. [3] The performances of the alkali metal-ion batteries depend much on the cathode and anode materials. Various types of cathode materials based on the reversible insertion/ extraction of alkali metal ions including transition metal oxides, fluorides, phosphates, hexacyanoferrates, and sulfates have been developed, and plenty of them exhibit desirable energy density and cycling performances. [4] Progress on the research for anode materials is relatively slow, however, as compared with their cathode counterparts. [5] Based on the reaction mechanisms, the anodes generally fall into three categories: insertion based, conversion based, and alloying based. [6] The conversion-based materials exhibit high theoretical specific capacities derived from the conversion reactions during the uptake of alkali metal ions. [7] Due to the large volume variations during charge/discharge, however, the conversion-based anodes exhibit rapid capacity fading. The alloyingbased materials deliver high specific capacity by the alloying reaction, but the material pulverization derived from repeated volume changes results in poor reversibility. [8] Insertion-based materials include titanium-based oxides and carbonaceous materials. Although the small volume change, high rate capability, and good cycling stability of titanium-based oxides are desirable, their high working voltages and low specific capacities are detrimental to the power density of the full cells. [9] Carbonaceous materials, including graphite, carbon nanotubes (CNTs), graphene, soft carbon (SC), hard carbon (HC), etc., are promising anode candidates for alkali metal-ion batteries. [10] Graphite has been developed as a practical anode for commercial LIBs. They have steady discharge curves and low operation potential (≈0.1 V vs Li + /Li), and the formation of stable graphite intercalation compounds (GICs) LiC 6 delivers a moderate theoretical intercalation capacity of 372 mAh g −1 . [11] While the intercalation capacities of graphite anodes for SIBs and PIBs are not satisfactory, delivering 35 mAh g −1 for SIBs with NaC 64Hard carbon (HC) is recognized as a promising anode material with outstanding electrochemical performance for alkali metal-ion batteries including lithium-ion batteries (LIBs), as well as their analogs sodium-ion batteries (SIBs) and potassium-ion batteries (PIBs). Herein, a comprehensive review of the recent research is presented to interpret the challenges and opportunities for the applications of HC anodes. The ion storage mechanisms, materials design, and electrolyte optimizations for alkali metal-ion batteries are illustrated in-depth. HC is particularly promising as an anode material for SIBs. The solid-electrolyte interph...

“…[115,116] GNSs hybridized with metal-based lithiophilic nanoparticles such as Co, Ni 3 N, Cu 2 O, and Au ones showed excellent electrochemical performance and effectively guided highly homogeneous metal deposition. [115][116][117][118][119] In particular, heteroatom-rich GNSs with Co nanoparticles showed a very low nucleation overpotential of ≈17 mV (Figure 7b), while NiN-hybridized nitrogen-rich GNSs showed stable Li plating/stripping cycling behavior for 1400 h at 1 mA cm −2 (Figure 7c). As carbon frameworks, commercial carbon papers/cloths were also hybridized with lithiophilic metal-based nanoparticles, [120][121][122][123] and carbon fibers coated with SnO 2 , [120] Ag, [121] and ZnO nanoparti-cles [122] as well as Co 3 O 4 nanofibers [123] were shown to be promising LMA materials (Figure 7d).…”

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.

“…[12][13][14][15][16] Among those diverse strategies, lightweight carbon-based hosts loaded with various lithiophilic transition metal elements as Li nucleation "seeds" are believed to be one of the promising routes. [17][18][19][20][21][22][23][24][25] For instance, Au, Ag, Zn, Mg etc. metal nanoparticles on carbon skeletons possessed essentially zero η value using as Li deposition substrates due to their certain solubility in metal Li and the formation of Li x M alloy phases.…”

In this work, the effects of the coexistence of Ni−Nx sites and Ni metal nanoparticles of Ni−N−C (nickel‐nitrogen‐carbon) materials on the thermodynamic Li nucleation overpotential (η) and kinetic exchange current density (j0) are systematically studied. Ni‐Nx sites guarantee reduced nucleation resistance on the hollow carbon sphere (HCS) host, while the low amount residual of Ni nanoparticles plays an adverse role. The Li nucleation overpotential was down to 10.6 mV and the exchange current density increased from 1.139 to 2.325 mA cm−2 when the residual Ni nanoparticles in the prepared Ni−N−C composite were removed. As a result, pure Ni‐Nx sites displayed an average CE of 98.4 % over 300 cycles and a stable Li plating/stripping behavior for over 800 h.
