The continual increase in energy demand and inconsistent supply have attracted attention towards sustainable energy storage/conversion devices, such as electrochemical capacitors with high energy densities and power densities. Perovskite oxides have…
A green, clean, and rapid process employing sunlight for converting a large quantity of graphene oxide (GO) into reduced graphene oxide (rGO) is presented herein. In this protocol, the sunlight is concentrated using a Fresnel lens and focused on GO,…
Either CoxSy transition metal sulfide or reduced graphene oxide (RGO) has become major electrode material for supercapacitor. Herein, nanostructured RGO@CoxSy composites were optimized by different sulfur sources and a one-step solvothermal method.…
The rapid depletion of fossil fuels has catalysed the research on alternative renewable energy resources and energy storage devices. Electrochemical energy storage (EES) devices have gained popularity among energy storage devices due to their…
The morphological and structural characteristics of material always play pivotal roles to be applied in energy storage and conversion applications. The conventional electrode materials are facing severe challenges, including (i) high commercial cost,…
Porous carbon (PC) derived from the petroleum pitch via the template-guidance coupled with activation methodology, possesses hierarchical pore structure in view of micropore and mesopore. As the electrode material for electrochemical double-layer…
