This paper raises several critical concerns that require clarification. The claims of significant enhancements in specific capacitance and cyclic stability for CuO-NiO-Co3O4 nanocomposites are not adequately substantiated due to insufficient experimental validation and the absence of quantitative metrics like BET surface area or comprehensive error analysis. Reported specific capacitance values appear unusually high compared to benchmarks, with no clear replication or control data provided. The electrochemical impedance spectroscopy lacks key parameters such as diffusion resistance, weakening the interpretation of charge transport mechanisms. Furthermore, citation mismatches and selective reporting undermine the study’s credibility, while a lack of engagement with recent advancements detracts from its relevance. These issues must be addressed to ensure the paper’s findings are reliable and transparent.
