- Abstract
Synthesis of phosphorus containing polyethers and their lithium-ion conductivities for the potential use as solid polymer electrolyte (SPE) in high-energy density lithium-ion batteries have been described. Co-polymerization of butyl bis(hydroxymethyl)phosphine oxide with three different dibromo monomers were carried out to produce three novel phosphorous containing polyethers ( P1- P3). These polymers were obtained via nucleophilic substitution reactions and were characterized by H, P NMR spectral data and gel permeation chromatography. SPEs were prepared using polyethers ( P1 and P2) with various amounts of lithium bis(trifluoromethanesulfonyl)imide (LiTFSI). The lithium-ion conductivity of SPE2 containing 40 wt% of LiTFSI was 2.1 × 10 S cm at room temperature and 3.7 × 10 S cm at 80°C. [Figure not available: see fulltext.]
