High performance polyvinyl alcohol/calcium titanate nanocomposite anion-exchange membranes as separators in redox flow batteries
Low ionic conductivity and poor chemical stability are the two key parameters that limit the use of many anion-exchange membranes in electrochemical applications like rechargeable batteries and fuel cells.

| description | Low ionic conductivity and poor chemical stability are the two key parameters that limit the use of many anion-exchange membranes in electrochemical applications like rechargeable batteries and fuel cells. Herein we report a method for the synthesis of a high performance anion-exchange membrane fabricated by incorporating calcium titanate nanoparticles (CaTiO
3
) into polyvinyl alcohol (PVA) matrix. The CaTiO
3
was synthesized by a new co-precipitation method from a solution of two simple precursors, viz potassium titanyl oxalate and calcium chloride. The XRD data of the synthesized nanoparticles indicate a phase pure orthorhombic perovskite structure. Morphological features investigated with SEM and TEM studies, reveal that the CaTiO
3
is having spherical shape with a diameter of approximately 200 nm. The PVA/CaTiO
3
nanocomposite membranes were fabricated by solution casting method from a well dispersed suspension of CaTiO
3
in PVA and characterized by FT-IR spectroscopy, TGA, SEM, AC impedance analysis and tensile strength measurements. The membranes with 30 wt% CaTiO
3
content possess ionic conductivity of 66 mS cm
−1
at room temperature. The electrochemical performance of an all-iron redox flow cell was studied using galvanostatic charge–discharge tests using the above nanocomposite membrane as separator and the system exhibited a coulombic efficiency of 75% during the charge–discharge cycles. |
