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.

Presently, two‐dimensional (2D) metal–organic framework (MOF) are drawing increasing attention in energy‐storage areas. However, more and complexed factors would affect the nucleation growth of 2D MOFs, subsequently final performance. Particularly, it is important to control coordination rate between ions ligands. In this paper, MXene was directly used as titanium source coordinate with an organic ligand form Ti‐MOF sheets. To further boost performance, mesopores were introduced preparing Ti‐MOF, constructing hierarchical porous Ti‐MOF@Ti 3 C 2 T X hybrids. Results showed that diffusion‐controlled behaviors play a dominant role over surface capacitive during charge storage process A hybrid supercapacitor (HSC) assembled obtained HP‐Ti‐MOF@Ti activated carbon (AC) exhibited energy density 22.9 Wh kg −1 at power 850 W (1 g ), 4.25 kW 15.3 (5 ). The present strategy expected provide design ideas for novel electrode materials.
