Supercapacitors offer notable advantages in the contemporary energy and environmental context due to their affordability, fast charging and discharging capabilities, long-term stability, and high power density. However, a pivotal challenge lies in developing electrode materials that exhibit superior electrochemical behaviour remains a challenge. Recent strides in this pursuit have brought to light the promising potential of NiCo2X4 (where X denotes O, S, or Se), owing to their cost-effectiveness, noteworthy redox reactions, and inherent electrical conductivity. This review meticulously provides an in-depth analysis of NiCo2X4, including its crystal structure, charge storage mechanism, and electrochemical performance. The main focus is on developing composites using NiCo2X4, and the review evaluates recent progress and suggests potential solutions to overcome challenges associated with supercapacitor electrodes. The review examines current advancements and proposes potential solutions to address ongoing challenges associated with supercapacitor electrodes. Through this exploration, the review not only provides valuable insights into the field's present state but also sheds light on future prospects, contributing to the continuous evolution of supercapacitor technology. |
