A one-step method preparing of poly(vinylidene fluoride)-based electrospun membranes (PEMs) containing TiO has been developed. The effect of TiO on the morphology, degree of crystallization and electrochemical behavior of PEMs was investigated by scanning electron microscopy (SEM), atomic force microscopy (AFM), differential scanning calorimetry (DSC) and electrochemical measurements. The PEMs containing TiO show improved ionic conductivity and cycling performance compared with pure PEMs.
