Li₇P₃S₁₁ is considered one of the most promising sulfide-based solid electrolytes for all-solid-state lithium batteries (ASSLBs) however, its complex crystallization dynamics present challenges in achieving maximum ionic conductivity. In this work, a comprehensive thermal and kinetic study elucidates the crystallization behavior of amorphous Li 7 P 3 S 11, focusing on how controlled nucleation and growth dynamics governs its structure–property relationships. Non-isothermal differential scanning calorimetry (DSC) combined with Kissinger, Ozawa, Matusita, and local activation energy models reveals crystallization activation barriers (E a ≈ 230–280 kJ.mol −1 ), highlighting a thermally activated, multi-stage transformation mechanism. A two-step heat treatment protocol, consisting of nucleation at 180 °C for 30 min followed by crystallization at 250 °C, substantially improves structural coherence and microstructural homogeneity. This kinetic tailoring leads to superior electrochemical performance, with room-temperature ionic conductivity reaching 1.98 mS·cm −1 and a Li + diffusion activation energy barrier of 0.25 eV. Structural and morphological analyses performed using X-ray diffraction (XRD) and field emission scanning electron microscopy (FESEM) confirm that controlled nucleation promotes uniform crystallite formation. These findings demonstrate that nucleation engineering is an effective strategy for enhancing crystallization pathways and unlocking the full potential of Li 7 P 3 S 11 and related glass–ceramic electrolytes in next-generation ASSLBs. • Li 7 P 3 S 11 synthesized mechanochemically and crystallized via DSC guided heating. • Two-step thermal treatment enhances ionic conductivity to 1.81 mS cm −1 at 25 °C. • Crystallization kinetics assessed by Kissinger, Ozawa, and Matusita models. • Local E a (230–280 kJ/mol) reveals nucleation and growth-controlled stages. • Controlled nucleation reduces grain-boundary resistance, enabling Li + transport.

LiMnxFe1-xPO4 (LMFP) is a promising olivine cathode material successor to LiFePO4, offering a higher operating voltage platform for enhanced energy density. However, its commercial application is hindered by inherent poor kinetics. Herein, a dual-site doping strategy involving Na+ and Co2+ is proposed to synergistically enhance the ionic and electronic conductivity of LMFP. The codoped LMFP-Na-Co cathode delivers a specific capacity of 135.8 mAh/g at 1 C and exhibits outstanding cycling stability with 92.5% capacity retention after 200 cycles. Remarkably, it also maintains 90.2% capacity retention after 300 cycles even at 0 °C. Theoretical calculations reveal that Na+ doping expands the one-dimensional lithium-ion diffusion channels, while Co2+ doping elevates the intrinsic electronic conductivity and suppresses the Jahn-Teller distortion associated with Mn3+, collectively lowering the Li+ diffusion barrier and improving structural stability. This work demonstrates that Na+-Co2+ dual-site doping is a highly promising strategy for developing high-performance LiMnxFe1-xPO4 cathodes.

The limitations of ion transport kinetics in conventional electrolytes, particularly under extreme operating conditions, arise from suboptimal solvation structures and inefficient charge carrier utilization. Here, we present strategic electrolyte design that reconfigures Li⁺ coordination geometry by modulating intermolecular interactions and solvent molecule volume, fundamentally overcoming these transport constraints. By incorporating an optimized moderator with a low dipole moment and small molecular size, extensive anion aggregation is effectively disrupted into compact ion conduction domains, simultaneously increasing the number of free charge carriers and enhancing ion mobility. Guided by this principle, the designed electrolyte with dichloromethane (85.11 Å, 2.36 Debye) exhibits rapid Li+ hopping between adjacent coordination sites (152.3 ps for acetonitrile and 115.7 ps for FSI-). This electrolyte enables stable cycling of 1.0 Ah 4.5 V graphite (3.13 mAh cm-2)||LiNi0.8Mn0.1Co0.1O2 (2.85 mAh cm-2) pouch cells, delivering 0.87 Ah at -40 °C, surpassing commercial carbonate-based electrolytes, which fail to retain reversible capacity at this temperature. This study establishes fundamental principles for fast ion-transport electrolytes, paving the way for next-generation Li-ion batteries under extreme scenarios.

Although energy density and cycling stability remain central to lithium metal battery (LMB) research, particularly in solid-state systems, two critical yet underappreciated challenges are wide-temperature operability and recyclability. These key parameters are fundamentally governed by electrolyte design. Here, we introduce a persistent-range hydrogen-bonded (PHB) gel polymer electrolyte (GPE) for LMBs. Constructed via continuous hydrogen-bonding interactions between perfluorinated branches and ─NH─ groups on fluorinated polyurethane backbones, this dynamic network architecture synergizes seemingly incompatible properties: chemically cross-linked–level mechanical robustness and chemical stability, alongside physically cross-linked–level dynamicity and ionic conductivity (8.6 mS cm−1 in regular carbonate electrolytes). The resulting PHB-GPE endows Li-metal pouch cells with stable cycling across a −60° to 100°C temperature range. Moreover, PHB-GPE exhibits recyclability potential, enabling the reuse of the Li salt and polymer at the end of battery life. These findings provide transformative insights into designing multifunctional GPE structures for next-generation LMBs, addressing both performance and sustainability imperatives.
