Functional materials with designer morphologies are anticipated to be the next generation materials for energy storage *** this manuscript,we have developed a holistic approach to enhance the surface area and hence the properties of nanostructures by synthesizing coronal nanohybrids of *** nanohybrids provide distinctive advantages in terms of performance and stability over vertically stacked nanocomposites reported in *** double hydroxide materials self-assembled as coronal lamellae on graphene shells have been synthesized and systematically *** coronal nanohybrids result in about a threefold increase in energy storage capacity as compared to their traditionally synthesized nanocomposite *** 3D graphene-based nanofibrils in the synthesized coronal nanohybrids provide mechanical support and connect the nodes of the double hydroxide lattices to inhibit *** morphologies such as coronal nanostructures increase the interaction surface of the nanostructure *** an approach is also expected to bring a paradigm shift in development of functional materials for various applications such as sensors,energy storage,and catalysis.
