Nickel cobalt sulfide (NiCo2S4) has attracted considerable interest as electrode material for supercapacitors owing to its distinct physical and chemical characteristics. However, the practical applications of pristine NiCo2S4 have been limited by issues such as small specific surface area, agglomeration, and volume changes during cycling, leading to low specific capacitance/capacity and cyclic stability at high rates. Several efforts have been taken to address these challenges.

1 Introduction Global energy consumption has risen, fueled by factors like population growth, industrial expansion, and rapid technological progress. Amid concerns over climate change and the gradual exhaustion of fossil fuel reserves, there is a global shift toward renewable energy sources, particularly solar and wind. However, the variability of these sources presents challenges for maintaining a stable and reliable power grid.

Nickel Cobalt Phosphate/Phosphide as Promising Electrode Materials for Extrinsic Supercapacitors: Machine Learning Analysis Recently transition metal compounds containing phosphorous, such as metal phosphates and phosphides have attracted great attention for energy storage devices such as supercapacitors. Benefiting from high ion conductivity, good chemical stability, and metalloid properties, metal phosphates and phosphides hold a promise to deliver excellent charge storage capacity.
