    Supercapattery is a combination of battery and supercapacitor in which one electrode is of battery and another electrode is of supercapacitor. The purpose of this study is to combine the merits of both supercapacitor and rechargeable battery into composite or uniquely structured material for making high performance electrode which can posse high energy-density as much as the battery output a power almost as high as supercapacitor. Activated carbon used as battery electrode is prepared from biomass(orange peel).Activated carbon is extracted from orange peel. Nickel Sulfide used as supercapacitor electrode is also prepared by microwave method. Nickel Sulfide is prepared by using thiourea and Nickel acetate. This is carried out by microwave method. The extracted activated carbon and synthesized nickel sulfide were analyzed for chemical and structural analysis by electrochemical measurements. During this process NiS and LC fiber sheets are also prepared. The CV results shows distinctive redox reactions. As scan rate is increased current is also increased. FTIR was also performed. FTIR was performed to check functional groups. All these characterization techniques confirm that activated carbon and nickel Sulfide are environmentally friendly materials.
