CARBON: Hexagonal carbon, characterized by its honeycomb-like lattice structure, are suitable for energy storage applications. Its high surface area, excellent electrical conductivity, and mechanical stability enable efficient charge transfer and rapid ion diffusion. The hexagonal arrangement provides abundant active sites for adsorption and redox reactions, enhancing capacitance and energy density in supercapacitors and batteries. Furthermore, its lightweight nature and chemical stability ensure long-term durability under repeated charge-discharge cycles. Modified hexagonal carbon nanostructures, such as doped graphene and carbon nanotubes, further improve storage capacity, making it a promising material for next-generation sustainable energy storage devices.
