“…Bai et al [82] measured the "experimental Sand's time" from the voltage-time plots at various current densities in a glass capillary cell using in situ snapshots (Figure 4e,f). The "Sand's capacity", C Sand , was raised following a formula shown in Equation (12). The authors proposed two mechanisms of lithium growth in liquid electrolyte (Figure 4g).…”

“…In the past decades, numerous efforts have been devoted to tackle the above-mentioned challenges, chiefly in the following five aspects: 1) constructing artificial SEI (ASEI) layers; [9][10][11][12][13] 2) introducing electrolyte additives; [14][15][16][17] 3) engineering modified separators; [18][19][20] 4) replacing liquid electrolytes with solidstate electrolytes; [6,[21][22][23][24][25][26] and 5) designing 3D host current collectors (Figure 1b). [27][28][29] ASEI layers can facilitate uniform Li plating/stripping, but challenges remain in constructing robust ASEI with desired ionic/electronic conductivity.…”

Lithium metal batteries (LMBs) have the potential to be the next‐generation rechargeable batteries due to the high theoretical specific capacity and the lowest redox potential of lithium metal. However, the practical application of LMBs is hindered by challenges such as the uncontrolled growth of lithium dendrites, unstable solid electrolyte interphase (SEI), and excessive volume change of Li metal. To solve these issues, the design of high‐performance lithium metal anodes (LMAs) with various 3D structures is critical. Targeting at realizing the “bottom–up” Li deposition to fully utilize the 3D architecture, in recent years, strategies such as gradient host materials construction, magnetic field modulation, SEI component design, and so on have attracted intensive attention. This review begins with a fundamental discussion of the Li nucleation and deposition mechanism. The recent advances in the aspects of construction strategies and modification methods that enable the “bottom–up” Li deposition within advanced 3D host materials, with a particular emphasize on their design principles are comprehensively overviewed. Finally, future challenges and perspectives on the design of advanced hosts toward practical LMAs are proposed.

“…Dispersing mechanically robust inorganic electrolyte fillers is believed to be the most effective method to hinder polymer crystallization, thus increasing the ionic conductivity and improving the mechanical strength of GPEs. Among these inorganic fillers, including inert types (e.g., Al 2 O 3 , [24] SiO 2 [25] and TiO 2 ) [26] and active types (e.g., Li 3 N, [27] Li 7 La 3 Zr 2 O 12 [LLZO], [28,29] and Li 1.3 Al 0.3 Ti 1.7 (PO 4 ) 3 ), [30][31][32] LLZO is more advantageous in virtue of its good contact stability with lithium anode and high ionic conductivity at room temperature. [28,33,34] Furthermore, developing nanostructured fillers, especially 1D nanowires with increased surface area and continuous ionic transport pathways can further increase the ionic conductivity of GPEs and reduce the junction cross significantly.…”

All‐solid‐state lithium metal batteries (LMBs) are regarded as one of the most viable energy storage devices and their comprehensive properties are mainly controlled by solid electrolytes and interface compatibility. This work proposes an advanced poly(vinylidene fluoride‐hexafluoropropylene) based gel polymer electrolyte (AP‐GPEs) via functional superposition strategy, which involves incorporating butyl acrylate and polyethylene glycol diacrylate as elastic optimization framework, triethyl phosphate and fluoroethylene carbonate as flameproof liquid plasticizers, and Li7La3Zr2O12 nanowires (LLZO‐w) as ion‐conductive fillers, endowing the designed AP‐GPEs/LLZO‐w membrane with high mechanical strength, excellent flexibility, low flammability, low activation energy (0.137 eV), and improved ionic conductivity (0.42 × 10−3 S cm−1 at 20 °C) due to continuous ionic transport pathways. Additionally, the AP‐GPEs/LLZO‐w membrane shows good safety and chemical/electrochemical compatibility with the lithium anode, owing to the synergistic effect of LLZO‐w filler, flexible frameworks, and flame retardants. Consequently, the LiFePO4/Li batteries assembled with AP‐GPEs/LLZO‐w electrolyte exhibit enhanced cycling performance (87.3% capacity retention after 600 cycles at 1 C) and notable high‐rate capacity (93.3 mAh g−1 at 5 C). This work proposes a novel functional superposition strategy for the synthesis of high‐performance comprehensive GPEs for LMBs.

Solid‐state batteries (SSBs) are under development as high‐priority technologies for safe and energy‐dense next‐generation electrochemical energy storage systems operating over a wide temperature range. Solid‐state electrolytes (SSEs) exhibit high thermal stability and, in some cases, the ability to prevent dendrite growth through a physical barrier, and compatibility with the “holy grail” metallic lithium. These unique advantages of SSEs have spurred significant research interests during the last decade. Garnet‐type SSEs, that is, Li7La3Zr2O12 (LLZO), are intensively investigated due to their high Li‐ion conductivity and exceptional chemical and electrochemical stability against lithium metal anodes. However, poor interfacial contact with cathode materials, undesirable lithium plating along grain boundaries, and moisture‐induced chemical degradation greatly hinder the practical implementation of LLZO‐based SSEs for SSBs. In this review, the recent advances in synthesis methods, modification strategies, corresponding mechanisms, and applications of garnet‐based SSEs in SSBs are critically summarized. Furthermore, a comprehensive evaluation of the challenges and development trends of LLZO‐based electrolytes in practical applications is presented to accelerate their development for high‐performance SSBs.
