“…During the Li stripping/depositing, the large pore volume and surface area of the NPC matrix could mitigate the anode volume change and suppress dendrite formation. Zhou and co‐workers used cobalt oxide (CoO) nanofibers to increase the lithiophilicity of Ni foam . Due to the high lithiophilicity of the CoO nanofiber‐decorated Ni foam (CONF), molten Li could rapidly infuse into it via a simple infusion process.…”

“…Therefore, designing high‐surface‐area composite anode can lower J and thus prolong the cell lifetime. Based on this theory, Cu mesh, Ni foam, and other 3D conductive frameworks have been developed to replace planar current collectors such as copper foil to fabricate 3D Li/current collector composites, lowering the local current density along the anode and serving as Li host to suppress electrode volume change upon cycling. However, due to the fast charge kinetics of the conductive frameworks, lithium ions prefer to deposit on the surface of the 3D matrix, which gradually leads to loose structure beneath the deposited lithium layer.…”

of lithium metal batteries (LMBs). [3][4][5] Compared with intercalation compounds such as graphite in LIBs, lithium metal anode possesses an extremely high theoretical capacity of 3860 mA h g −1 with a very low redox potential (−3.04 V vs the standard hydrogen electrode), making it an attractive anode material to pair with highenergy conversion cathodes such as sulfur and oxygen. [6,7] Unfortunately, the application of lithium metal is full of challenges that have puzzled researchers for more than 40 years. [8] The most notorious one is that Li metal problematically forms dendrites during repeated cycling. [9] Owing to the multi-component solid electrolyte interphase (SEI) layer and uneven anode substrate, inhomogeneous lithium-ion flux is formed at the electrode/electrolyte interface, leading to nonuniform lithium eletrodeposition on the metal surface. The fresh metallic tip acts as an active site, which induces the ramified growth of lithium dendrite, resulting in cell short-circuit and low coulombic efficiency. This dendrite formation behavior can be much severe at high current densities. Another serious problem lies in electrode volume expansion originated from the repeated plating/ stripping process. [10,11] As a "hostless" electrode, lithium metal tends to be fully stripped when used in practical full cells and can hardly travel back to the same location during plating, causing mechanical instability of electrode/separator interface as well as internal stress fluctuation. As a result, the capacity of LMBs fades sharply during cycling.Over the past four decades, many up-and-coming strategies have been developed to enhance the electrochemical performance of Li metal anode and overcome the problems raised from uneven Li electrodeposition. These methods include doping electrolyte additives (Li halide, [12] ionic liquid, [13] and Cs +[14] ) and coating artificial SEIs (Li 3 PO 4 , [15] Cu 3 N, [16] LiF, [17] and Li alloy [18][19][20] ) on Li anode. More recently, researchers have focused on creating 3D scaffold/lithium metal composites as alternatives for common planar lithium. According to Chazalviel's model, the onset time of uneven deposition is inversely proportional to the current density (τ ≈ -2 J ). [21,22] Therefore, designing high-surface-area composite anode can lower J and thus prolong the cell lifetime. Based on this theory, Cu mesh, [23,24] Ni foam, [25] and other 3D conductive frameworks [26][27][28] have been developed to replace planar current The lithium metal battery (LMB) is among the most sought-after battery chemistries for high-energy storage devices. However, LMBs usually undergo uncontrollable lithium deposition and severe side reactions, which significantly impede their practical applications. Herein, a stable Al 2 O 3 -based inorganic framework with superlithiophilic lithium aluminum oxide (Li-Al-O) interphase is created via reacting Li with Al 2 O 3 nanoparticles. The Al 2 O 3 -based inorganic framework can serve as a stable Li "host," reducing the volume expansion during cell cyclin...

“…Beyond sulfur cathode, many approaches have been reported to obtain stable Li anodes, including developing Li hosts with lithiophilic surfaces, using new electrolyte additives and fabricating artificial solid electrolyte interface (SEI) layers . Among them, metallic oxides (e.g., CoO and ZnO) have been widely used to realize uniform Li nucleation due to the lithiophilic feature . Nevertheless, metallic nitrides with high conductivity and strong affinity to lithium have been seldom reported.…”

Lithium-sulfur (Li-S) batteries have been regarded as the most promising candidates as the next-generation energy storage systems because of high theoretical capacities (Li: 3860 mAh g −1 and S: 1675 mAh g −1 ), low mass densities (Li: 0.534 g cm −3Lithium-sulfur (Li-S) batteries are strongly considered as next-generation energy storage systems because of their high energy density. However, the shuttling of lithium polysulfides (LiPS), sluggish reaction kinetics, and uncontrollable Li-dendrite growth severely degrade the electrochemical performance of Li-S batteries. Herein, a dual-functional flexible free-standing carbon nanofiber conductive framework in situ embedded with TiN-VN heterostructures (TiN-VN@CNFs) as an advanced host simultaneously for both the sulfur cathode (S/TiN-VN@CNFs) and the lithium anode (Li/TiN-VN@CNFs) is designed. As cathode host, the TiN-VN@CNFs can offer synergistic function of physical confinement, chemical anchoring, and superb electrocatalysis of LiPS redox reactions. Meanwhile, the well-designed host with excellent lithiophilic feature can realize homogeneous lithium deposition for suppressing dendrite growth. Combined with these merits, the full battery (denoted as S/TiN-VN@ CNFs || Li/TiN-VN@CNFs) exhibits remarkable electrochemical properties including high reversible capacity of 1110 mAh g −1 after 100 cycles at 0.2 C and ultralong cycle life over 600 cycles at 2 C. Even with a high sulfur loading of 5.6 mg cm −2 , the full cell can achieve a high areal capacity of 5.5 mAh cm −2 at 0.1 C. This work paves a new design from theoretical and experimental aspects for fabricating high-energy-density flexible Li-S full batteries.
