ABSTRACT The coordinated development of materials for energy conversion and storage is necessary due to the rising demand for energy worldwide. This article discusses the advancements made in the direction of graphene oxide based halide perovskite electrode for energy storage device. Specially, Graphene oxide based halide perovskite electrode is being deliberated as the potential electrode materials for great power supercapacitor application due to its exceptional chemical and physical characteristics, including high electrical conductivity and a huge surface area. In the development of high‐performance supercapacitors, graphene oxide and halide perovskites have demonstrated encouraging outcomes. Because of their huge surface area and superior electrical conductivity, graphene‐based materials are very sought‐after for supercapacitors. According to a study, an aqueous electrolyte with tailored three‐dimensional graphene frameworks can have a superior gravimetric capacitance of 330 F g −1 . Organic and gel electrolytes were among the electrolytes used to test this performance; the latter demonstrated an outstanding capacitance of 285 F g −1 along with outstanding rate capability and cycle life. The maximum energy density of around 22 Wh kg −1 and power density of 900 W kg −1 for the supercapacitor were achieved with a particular ratio of bromide to iodide in the perovskite materials. Incorporating GO into CH 3 NH 3 PbI 3 perovskite layers improved humidity resistance and device lifespan by acting as a water diffusion barrier. Our review article will comprise of Structure, dimensionality, properties, supercapacitor & classification, 2D, 3D & graphene oxide based halide perovskite materials for supercapacitor, challenges/ limitation, Future Scope of supercapacitor in brief.
