Abstract To enhance the electrochemical performance of NiMn‐LDHs electrode materials, this study explores metal Co doping and synthesizes nano‐onion‐like NiCoMn‐LDHs composites. By examining effects various heat treatment temperatures (100°C, 110°C, 120°C, 130°C, 140°C), we identified that prepared at 130°C exhibited superior performance. The results reveal significantly increases specific capacitance compared with undoped NiMn‐LDHs. achieved a 4413 F g 1 A −1 maintained 3055 10 , demonstrating excellent rate These findings highlight benefits optimized for improving in supercapacitor applications, providing strong foundation their use high‐performance energy storage devices.
