The excellent electrochemical stability, high specific capacitance, cost-effectiveness, and compatibility with other conductive materials make nickel iron-layered double hydroxide (NiFe-LDH) a promising electrode material. However, low electrical conductivity, restricted ion mobility, difficult synthesis, scaling issues limit its application in supercapacitors. characteristics of NiFe-LDH are significantly improved when combined carbonaceous materials, such as carbon nanotubes (CNT), leading to increased rate performance, enhanced charge storage capacity. With this motivation, cost-effective, facile, scalable synthesis protocol has been devised prepare bare MWCNT-loaded composites employing the hydrothermal method at 180 °C. Thereafter, electrodes were fabricated using as-synthesized screen-printing process. findings revealed that inclusion CNTs into stability capacity, NiFe-LDH@CNT demonstrated an capacitance (Cs) 1243 F g–1 (522 C or 138 mAh g–1) retention (CR) 87% after 6000 number cycles (N), compared (Cs = 834 CR ∼ 73% N 6000). remarkable improvement is endorsed by effective integration CNTs, forming distinctive composite superior properties for supercapacitor applications. An asymmetric power density 1136 W kg–1 energy 57.6 Wh was cathode activated (AC) anode. performance supercapacitors (ASCs) evaluated powering digital thermometers prolonged periods, demonstrating their versatility
