    Poly (vinyl ethylene carbonate) electrolyte with superior ionic conductivity of × 10 −3 S cm −1 at 25 °C has been designed.. The lithium battery with LiFePO 4 can deliver high discharge capacity about mA h g −1 at 25 °C, and mA h g −1 at −15 °C.. The ions transport reaction mechanism has been revealed from the coupling/decoupling between Li ions and oxygen atoms.   In terms of practical application, PEDOT:PSS is the most successful conductive polymer, and has found uses in many electrochemical applications. Recently, researchers focusing on Li–S batteries have applied PEDOT and PEDOT:PSS to Li–S cathodes in order to produce electronically conductive polymeric binding by:
