NiAl LDH Based Nanocomposites for Supercapacitor Application: Review

The growing need for efficient and sustainable energy storage technologies has driven extensive research toward the development of high-performance electrode materials for supercapacitors. Among various candidates, nickel-aluminum layered double hydroxides (NiAl-LDHs) have emerged as promising materials owing to their notable redox behavior, high surface area, and favorable electrochemical performance. This chapter focuses on the preparation of NiAl-LDH-based nanocomposites through a hydrothermal synthesis route and examines their structural features, surface morphology, and electrochemical behavior for energy storage applications. Structural analysis confirms the formation of layered double hydroxide phases, while morphological studies reveal nanosheet-type structures with high surface accessibility. Electrochemical measurements indicate strong pseudocapacitive behavior and good charge storage capability. A comparative study with previously reported NiAl-LDH based materials further highlights their potential as efficient electrode materials for supercapacitor applications.
