Abstract

In this article, we propose a simple redox process to in-situ create a cellular architecture on Ni solid sheet by the direct oxidization (O₂) and subsequent reduction (H₂) at 750 °C. Nanocrystalline Ni(OH)₂ is fabricated on the micro-porous Ni sheet (MPNS) using cathodic electrodeposition method to form a MPNS-Ni(OH)₂ electrode for supercapacitor. The obtained results indicate that the created micro-porous architectures expand the contact interfaces between the Ni(OH)₂ and Ni substrate and enhance its supercapacitor performance and cyclic stability.
