Superior charge storage performance of optimized nickel cobalt
In our work, we report superior electrochemical performance of optimized 3D nanostructured, nickel-cobalt carbonate hydroxide hydrate (Ni 3 − x Co x -CHH (1 ≤ x ≤ 2))
This highlights the Nickel cobaltite-based composite material's diverse morphologies and excellent electrochemical performance for supercapacitor applications. The morphology of materials used in supercapacitors greatly influences their performance.
Although numerous strategies, such as hierarchical structure design, component optimization, and hybridization, have been deployed to overcome the limitations of nickel-based supercapacitors and have notably enhanced their performance, challenges persist (Fig. 8).
Nickel-based electrode materials, in contrast, offer high-specific capacitance—a feature not inherent in carbon materials. Consequently, there has been a surge in research efforts aiming to construct symmetric supercapacitors using high-capacity nickel-based compounds and their composites.
