A carbon felt is dipped into an inorganic-organic hybrid sol, dried, and heat-treated at 600 degrees C for 2 h in a flowing argon. Coated surface of the felt has been examined by scanning electron microscopy (SEM) equipped with energy dispersive X-ray spectroscopy (EDX) and scanning transmission electron microscopy (STEM). The cell prepared with the coated carbon felt shows 92% of charge acceptance and 99.9% of coulombic efficiency at 100 mA cm(-2) of current density. (C) 2016 Elsevier B.V. All rights reserved.
