Nowadays, being able to store and recover energy quickly is becoming increasingly more important for different applications. This Study report on novel electrode material composed of MWCNTs directly synthesized over a fine aluminum foil in CVD then functionalized with Nitric Acid and placed in Coin cells. The electrolyte used was an aqueous solution of Lithium Sulfate 1Mol/L with Sonicator-scattered Pani. This Material showed a good lifetime, solid electric potential stability until 2V and
