Abstract

Liquid-free solid polymer electrolyte (SPE) Li-O₂ batteries are considered advantageous power sources for multiple applications, albeit their cycle performance is far from being acceptable. A most challenging SPE stability in Li-O₂ battery operating at 80 °C is described here, presenting possible directions for this battery type future development. Hereby, we investigated poly(ethylene oxide) (PEO) stability in Li-O₂ batteries after cycling and determined that the polymer instability is originated from an accumulation of formate-based species, which required high decomposition potential and showed low decomposition efficiency. This poses a key challenging issue of unfavorable round-trip efficiency, dictating a poor cycle performance.
