Design and characterization of asymmetric supercapacitor useful in hybrid energy storage systems for electric vehicles

Barzegar, Farshad; Momodu, Damilola Y.; Zhang, Lijun; Xia, Xiaohua; Manyala, Ncholu I. (Elsevier, 2017-12)

Energy storage systems (ESSs) of electric vehicles (EVs) require high energy density and high power density concurrently. The ESSs with only supercapacitors (SCs) or high performance batteries (hpBs) have egregious ...
A high energy density asymmetric supercapacitor utilizing a nickel phosphate/graphene foam composite as the cathode and carbonized iron cations adsorbed onto polyaniline as the anode
