Layered double hydroxide (LDH) has a layered structure, which makes it strong candidate for supercapacitors (SC) due to its high surface area. However, they suffer from low conductivity insufficient charge transfer across their layers. This research aims overcome this obstacle by introducing conductive channels among the layers addition of Ag–citrate and polyaniline (PANI). Consequently, five electrodes (S 1–5 ) were made NiCoMn LDH (referred as henceforth) 2:1 PANI composite (Ag/PANI) in different ratios into electrodes. Electrochemical analysis revealed successful improvement performance fraction Ag/PANI increased until equaled where highest specific capacitance 617 F g −1 was obtained, is 12% greater than value solely electrode (550 ). A device fabricated with best 3 activated carbon electrode, demonstrated energy densities power 41 WhKg 412.5 W Kg 14 8250 at 0.5 10 current densities, respectively. It also exhibited capacitive retention about 75% 3000 galvanostatic charge–discharge cycles. These results encourage use LDH, 1:1 ratio SCs remarkable performance.
