Spear-shaped Mn/Ni bimetallic hydroxide derived from metal-organic frameworks as electrode materials for aqueous and all-solid-state hybrid supercapacitors

Conductive NiMn-based bimetallic metal–organic gel nanosheets for supercapacitors

“…These values are comparable or better than those recently reported by other ASC devices (Fig. S10) such as LaMnO 3 @NiCo 2 O 4 / Ni // AC 43 (36.6 W h kg -1 at 800W kg -1 ), MnNiDH // AC 44 (58.53 W h kg −1 at 0.8 kW kg −1 ) and NiCoMn LDH / rGO // AC 45 (92.8 W h kg −1 at 0.46 kW kg −1 ), Mn 0.1 -Ni-MOF // AC 46 (39.6 W h kg -1 at 143.8 W kg -1 ). Furthermore, after the assembled ASC device is charged/discharged for 5000 times, the capacitance still remains at 84.6 %, and exhibits an excellent cycle life (Fig.…”

Dual-ligand strategies to assemble S, N-containing metal organic framework nanoflowers for hybrid supercapacitors

“…The value of the intercept between the semicircular arc and the real axis in the high-frequency region corresponds to the internal resistance of the electrode material ( R s , including the intrinsic resistance of the active material, the ionic resistance of the electrolyte, and the contact resistance of the active material with the collector). 53 In addition, the equivalent circuit diagram is fitted for a clear understanding of the electrochemical reaction between the electrode and electrolyte. The fitting results almost coincide with the experimentally obtained plots.…”

Efficient Metal‐Oriented Electrodeposition of a Co‐Based Metal‐Organic Framework with Superior Capacitive Performance

“…Both b values approached 0.5, proving the electrochemical process of Co-MOF/CFC was governed by diffusion-controlled intercalation behavior. In addition, the percentage of capacitive contribution and diffusion-controlled contribution at different scan rates were further analyzed by using Equation ( 4): [38][39][40] iðVÞ…”
