Trends on the Development of Hybrid Supercapacitor Electrodes from the Combination of Graphene and Polyaniline

The high demand for efficient energy devices leads to the rapid development of storage systems with excellent electrochemical properties, such as long life cycles, cycling stability, and power density. SC is postulated a potential candidate fulfill this demand. combination graphene polyaniline can create electrodes electrical conductivity, specific surface area, capacitance. graphene/polyaniline hybrid represent an attractive means overcome major drawbacks or non-hybrid (single) electrode materials. In review article, trend in various summarized, which includes zero-dimension graphene-quantum-dots/polyaniline hybrid, one-dimension two-dimension three-dimension hydrogel-shaped hybrid. Several strategies approaches enhance capacitance value stability are discussed addition transition metal oxides metal-organic frameworks, modification into functionalized-graphene. performance prepared from other conducting polymers (i.e., polypyrrole, polythiophene, polythiophene-derivatives) also discussed.
