Abstract The performance of asymmetric supercapacitors (ASCs) is strongly restricted by the capacity gap between positive and negative electrodes. To address this issue, two new electrode materials deriving from Co‐ Fe‐based metal–organic frameworks (MOFs, Co‐TAMBA‐d, Fe‐TAMBA‐d) through a single‐step sintering method have been developed considering superiorities derivatives MOFs including large surface areas, sufficient metal‐atom‐doping content, extreme wettability to bath solution. as‐prepared Co‐TAMBA‐d as delivers typical pseudocapacitive behavior with improvement capacity, which better than those pristine MOF materials, while Fe‐TAMBA‐d electrodes displays electrochemical activated carbon. ASCs based on these exhibits excellent energy density power 47 W h/kg 1658 W/kg, respectively, where device can maintain prominent cycling stability retention after 5000 cycles being about 75%. Furthermore, feed series red light‐emitting diodes, gives solid evidence potential utilization. These results afford feasibility isostructural promising in novel ASCs.

Nanocomposites containing Ni or Co NiCo alloy and nitrogen-doped carbon with diverse ratios have been prepared utilized as active elements in supercapacitors. The atomic contents of nitrogen, nickel, cobalt adjusted by the supplement amount salts. In virtue excellent surface groups rich redox sites, NC/NiCo materials exhibit superior electrochemical charge-storage performances. Among these as-prepared electrode materials, NC/NiCo1/1 performs better than other bimetallic/carbon electrodes pristine metal/carbon electrodes. Several characterization methods, kinetic analyses, nitrogen-supplement strategies determine specific reason for this phenomenon. As a result, performance can be ascribed to combination factors including high area nitrogen content, proper Co/Ni ratio, relatively low average pore size. delivers maximum capacity 300.5 C g-1 retention 92.30% after 3000 unceasing charge-discharge cycles. After assembling it into battery-supercapacitor hybrid device, energy density 26.6 Wh kg-1 (at 412 W ) is achieved, comparable recent reports. Furthermore, device also power four light-emitting-diode (LED) demos, suggesting potential practicability N-doped compositing bimetallic materials.
