Electrochemical impedance studies of lead oxide nano-dendrites prepared via electrochemical deposition and Polyethylene glycol soft-template

The shape-controlled synthesis of lead oxide nanodendrites (NDS) via electrochemical methods has been investigated in aqueous solution of PbNO۳ with the assistance of polyethylene glycole (PEG) as a soft template and its electrochemical performance on the lead acid battery electrodes was characterized by electrochemical impedance spectroscopy (EIS) technique. The morphology of the nanostructures mainly depends on the adjustable driving force of electrodeposition, such as the potential, the concentration of lead precursor (Pb²+), and the presence of inert electrolyte ions, while being modulated by PEG that contributes mainly to the finer structure in the shape-controlled synthesis. This unique structure provides an effective method for increasing the efficiency and capacity of the active material in lead-acid batteries.
