Abstract. Electrochromic materials are gaining considerable interest in energy storage owing to their dual ability to couple optical modulation with electrochemical performance. In this study, a nickel cobalt phosphate (NCP)/MXene (Ti3C2) composite was synthesized via a microwave-assisted hydrothermal route, with the concentrations of both components systematically optimized using central composite design (CCD). The optimized NCP/Ti₃C₂ electrode achieved a remarkable coloration efficiency of 132.68 cm² C⁻¹, excellent coloration stability with 70% retention after 1000 cycles, and a high specific capacitance of 2270 F g⁻¹ at 1 mV s⁻¹. These results demonstrate that the CCD-optimized NCP/Ti3C2 composite not only achieves superior electrochromic and energy storage characteristics but also offers a scalable pathway for the advancement of multifunctional energy storage platforms in wearable and smart electronic applications.
