Solid polymer electrolytes (SPEs) are promising candidates for lithium metal batteries (LMBs) owing to their safety features and compatibility with anodes. However, the inferior ionic conductivity electrochemical stability of SPEs hinder application in high-voltage solid-state LMBs (HVSSLMBs). Here, a strategy is proposed develop dual-anion-rich solvation structure by implementing ferroelectric barium titanate (BTO) nanoparticles (NPs) dual salts into poly(vinylidene fluoride) (PVDF)-based HVSSLMBs. The BTO NPs regulate spatial PVDF segments, enhancing local built-in electric field SPEs, which, turn, facilitates dissolution dissociation salts. This contributes an enhanced steric effect, which significantly improves Li+ transport kinetics stability. designed PVDF-based SPE achieves high 4.1 × 10–4 S cm–1 transference number 0.70 at 25 °C. Li//Li symmetric cells deliver excellent critical current density 2.4 mA cm–2 maintain stable Li plating/stripping process over 5000 h. After 1000 cycles 2C, LiFePO4//Li achieve discharge capacity 108.3 mAh g–1. Furthermore, LiNi0.8Co0.1Mn0.1O2 (NCM811)//Li present retention after 300 1C cutoff voltage 4.4 V. NCM811/Graphite pouch exhibit cycling performance. work illustrates that synergistic integration functional multiple holds significant potential development SPEs.

Lithium-oxygen (Li-O2) batteries with high energy density have given rise to tremendous advances in developing highly efficient storage devices. However, the barrier of Li dendrite growth and liquid electrolyte volatilization under semi-open architectures still restrict their future applications. Poly(vinylidene fluoride) (PVDF)-based polymer electrolytes are considered be an effective solution these issues, but presence reactive residual solvents severely disrupts long-term cycling stability battery. Herein, a tailoring strategy confine redistribute solvent molecules by introducing porous metal-organic framework (MOF) is proposed. The Lewis acid sites functional groups on MOFs offer more binding for solvents, leading involved anions Li+ solvation. Benefiting from tailored coordination environment electrolytes, effectively suppressed composite (MOF@PVDF). As result, MOF@PVDF enables Li//Li symmetrical cells ultra-stable over 800 h at 0.2 mA cm-2. Meanwhile, MOF@PVDF-based Li-O2 battery has realized long life above 1100 200 g-1. This work opens direction stable solvation structures electrolytes.
