Abstract

Typical ester-and ether-based polymer electrolytes are semi-crystalline and highly flammable, which brings potential fire risks during their application in lithium metal batteries. In this study, polyrotaxane (PLR)-based flame-retardant solid polymer electrolytes (SPEs) were designed and developed based on polyethylene oxide (PEO) via fully utilizing the dual effects of alpha-cyclodextrin (alpha-CD) as the host (for PLR) and the carbon source in phytic acid-derived charring flame-retardant systems. This work includes the following three aspects: (I) The molecular structure of SPE was tuned by adjusting the feeding order of alpha-CD. Thereinto, the optimized PLR-based electrolytes exhibited better mechanical strength and improved elasticity, which enabled its self-supporting property and improved interfacial compatibility; (II) Lithium phytate (PALi) was introduced for the first time to modify the flame retardancy of polymer electrolytes for lithium batteries by constructing the synergistic charring effect with alpha-CD. With 10 wt% PALi, the modified electrolyte can perform a comparable electrochemical performance with neat electrolyte, whereas the burning intensity has decreased significantly. The apparently reduced burning rate, peak heat release rate, total heat release, total smoke release, and increased char residue formation also proved the improved flame retardancy. In this work, the electrochemical performance and flame retardancy for the PALi-modified PLR-based SPE achieved a balance by a sustainable strategy. This valid synergistic charring effect of PALi and alpha-CD has been proved by systematic flame-retardant mechanism study through FTIR, Raman, and pyrolysis-gas chromatography-mass spectrometry.
