Lithium metal is considered one of the most promising anode materials for lithium batteries due to its high theoretical specific capacity (3860 mA h g-1) and low redox potential (-3.04 V). However, uncontrolled dendrite growth severe interfacial side reactions during cycling result in poor performance safety risks, significantly limiting practical applications. Replacing liquid electrolytes with solid polymer (SPEs) offers a solution, as SPEs provide flexibility good electrode compatibility, effectively inhibiting reducing reactions. Among SPEs, poly(vinylidene fluoride) (PVDF)-based offer excellent thermal stability mechanical strength, making them highly suitable high-energy-density flexible batteries. This review presents recent advances PVDF-based solid-state (SSEs) stable, high-performance (LMBs). We focus on modification strategies that enhance SSEs LMBs highlight how synthesis methods, nano/microstructural design, electrochemical properties are interrelated. Lastly, we discuss challenges prospects next-generation LMBs.

Abstract Growing market demands on portable electronics, electric vehicles, and energy storage system calls for the development of high‐energy density lithium (Li) batteries. Li metal is considered as a promising anode material owing to their high capacity low electrochemical potential. However, reactivity with conventional flammable liquid electrolytes easily forms dendrites, which may cause short‐circuit even catching fire, obstructing wide application Although non−/less‐flammable solid have replaced electrolytes, solid‐state batteries (SSLMBs) suffer from lower + conductivities, chemical/electrochemical incompatibilities toward metal, inhomogeneous flux at interfaces. Therefore, many researchers devoted themselves solve these problems. For better understanding current issues recent advances, this article provides (1) review various conductivity interfacial in SSLMBs, (2) progress stabilization interface between node including an electrolyte modification (e.g., composition, additives) introduction interlayer.

In this study, we investigated the structural effect of composite solid electrolytes Al-doped LLZO and PVDF-HFP (0D_Al-LLZO@PVDF-HFP 1D_Al-LLZO@PVDF-HFP) on electrochemical (EC) performance fire safety through a systematic evaluation comparative tests. The unique structure advantageous features (1D_Al-LLZO@PVDF-HFP) were highlighted by comparing controls (PVDF-HFP 0D_Al-LLZO@PVDF-HFP) with physicochemical analyses tests morphology LLZO/PVDF-HFP composites analyzed X-ray diffraction (XRD) scanning electron microscopy (SEM), while their chemical functionalities free ion clusters examined Fourier transform infrared (FT-IR) spectroscopy Raman spectroscopy, respectively. 1D_Al-LLZO@PVDF-HFP 1D structured Al-LLZO filler network in matrix could effectively regulate crystallinity facilitated lithium salt dissociation, resulting high lithium-ion transference number ionic conductivity. As result, electrolyte an optimized low content (~5.1 wt%) exhibited enhanced conductivity (σ: 1.40 × 10−4 S/cm) interfacial resistance, broadened EC stability (voltage window: 4.75 V vs. Li/Li+), (0.75) superior to that 0D_Al-LLZO@PVDF-HFP. characterizations, 1D_Al-LLZO@PVDF-HFP-based cell demonstrated symmetric (>2000 h) full (LiFePO4|electrolyte|Li) reversible capacity 102.7 mAh/g at 2C retention 85.7% over 200 cycles, better than 0D_ Al-LLZO@PVDF-HFP-based cell. flammability tests, Al-LLZO@PVDF-HFP (nonflammability) compared PVDF-HFP-based regardless structure, suggesting importance inorganic rather composite.
