“…Metal–organic frameworks (MOFs) are a unique kind of porous solid material that provide a high degree of chemical and structural tunability by judicious selection of inorganic nodes and organic linkers. MOFs have exhibited great potential applications as electrocatalysts − and in supercapatteries. ,,− However, since good electrical conductivity is one of the requisites for rapid charge storage, the poor electrical conductivity of most pristine MOFs far hinders the application of MOF-based electrodes in energy storage. Therefore, most MOFs have been utilized as precursors or templates for the preparation of porous carbons, , which destroys the original MOFs and usually requires harsh pretreatment conditions.…”

Metal–organic frameworks (MOFs) have attracted noticeable attention as promising candidates for electrochemical energy storage. However, the lack of electrical conductivity and the weak stability of most MOFs result in poor electrochemical performances. Here, a tetrathiafulvalene (TTF)-based complex, formulated as [(CuCN)2(TTF(py)4)] (1) (TTF-(py)4 = tetra(4-pyridyl)-TTF), is assembled by in situ generation of coordinated CN– from a nontoxic source. Single-crystal X-ray diffraction analysis reveals that compound 1 possesses a two-dimensional layered planar structure, which is further stacked in parallel to form a three-dimensional supramolecular framework. The planar coordination environment of 1 is the first example of a TTF-based MOF. Attributed to the unique structure and redox TTF ligand, the electrical conductivity of 1 is significantly increased by 5 orders of magnitude upon iodine treatment. The iodine-treated 1 (1-ox) electrode displays typical battery-type behavior through electrochemical characterizations. The supercapattery based on the 1-ox positrode and AC negatrode presents a high specific capacity of 266.5 C g–1 at a specific current of 1 A g–1 with a remarkable specific energy of 62.9 Wh kg–1 at a specific power of 1.1 kW kg–1. The excellent electrochemical performance of 1-ox is one of the best among those reported supercapatteries, demonstrating a new strategy for developing MOF-based electrode materials.

Novel electrode development is crucial in the hunt for long-term energy storage options. In this work, we describe a promising advanced energy storage system with the fabrication of a cobalt metal organic framework doped with zinc sulfide (Co-MOF/ZnS) as an electrode and applied to energy storage and hydrogen evolution reaction (HER) applications. The Brunauer− Emmett−Teller (BET) method showed a 65.32 m 2 /g surface area for Co-MOF/ZnS. The Co-MOF/ZnS electrode has an outstanding capacity of 1615 C/g in a three-electrode setup. Furthermore, when paired with activated carbon (AC) in a supercapattery, this device exhibits a remarkable energy density of 59.33 W h/kg and a power density of 812 W/kg. The cycling stability of the Co-MOF/ZnS//AC supercapattery is evaluated by subjecting it to 10,000 cycles. The Co-MOF/ZnS//AC supercapattery test is carried out shortly after the stability test, and it retains 98% of its original capacity while maintaining a high Coulombic efficiency of 87%. In the HER test, Co-MOF/ZnS exhibits an outstanding overpotential of 434 mV.

Summary The modern technology‐based hybrid energy storage devices (HESDs) in recent times, due to excelling collective features of secondary batteries (SBs) and supercapacitors, have attained the remarkable attention of scientific community throughout the globe. The metal sulfides and their composites among all electrode materials owing to their viable electrochemical characteristics have been recognized as important contender for hybrid devices.
