Abstract The ion conduction of a blend of poly(oxyethylene) (PEO) and lithium methoxy oligo(oxyethylene) sulfate (SAL8) and its electrochemical characteristics were studied. The maximum ambient conductivity of the blend reaches 1.2 × 10?6 S/cm. The blend exhibits single-ion conduction, excellent mechanical performance, and electrochemical stability. A battery of Li/PEO + SAL8/Li1+xV3O8 has a constant discharge capacity at different discharge current densities up to a certain voltage, while the discharge capacity of Li/P (MEO16-AM) + LiClO4/Li1+xV3O8 decreases with an increase of the discharge current density. |
