Now-a-Day's increasing demand towards the development of new novel material for energy and power application. Supercapacitor is one of the challenge filed in the current era. Scientist are developing the various energy and power storage device to mitigate the current challenge. The present study is focused on the Synthesis of Bismuth oxide using Potentiodynamic eleectrodeposion technique. Prepared samples were characterized physically and Electrochemical by CV, CP and EIS.
