“…As shown in Figure 14 a,b, MOF‐74 based on neat Ni, Co, and Ni–Co mixture have been employed as precursors, yielding the porous NiO, Co 3 O 4 , and NiCo 2 O 4 , respectively. [ 186 ] Although bimetallic oxides feature only a moderate SSA (59.6 m 2 g −1 for NiCo 2 O 4 , 227.5 m 2 g −1 for NiO, and 48.9 m 2 g −1 for Co 3 O 4 ), a considerable increase in specific capacitance has been observed (684 F g −1 for NiCo 2 O 4 , 105 F g −1 for NiO, and 181.5 F g −1 for Co 3 O 4 at 0.5 A g −1 ) and a capacitance of 362.4 F g −1 has been sustained at 10 A g −1 . The enhanced performance may be attributed to the coexistence of multiple charge‐storage mechanisms shown in the NiCo 2 O 4 , highlighting the importance of synergistic effect of multiple metals.…”

energy storage (EES)-primarily supercapacitors and metal-ion batteries (MIBs, e.g., lithium-ion batteries (LIBs), sodiumion batteries (SIBs), and potassium-ion batteries (PIBs)).Both supercapacitors and batteries typically consist of current collectors, electrodes, electrolyte, and a separator. By applying a suitable potential between current collectors, the charge/discharge process takes place mediated by the electrode materials, and the electrolyte ions (i.e., the charge carriers) are accordingly driven to travel across the separator so as to connect the circuit. In recent years, solidstate electrolytes (SSEs) are also under popular development to enhance cell voltage (energy density) and safety of the devices. [1] Upon charging, electrical energy is converted to electrostatic potential for supercapacitors and to chemical energy for batteries, and vice versa. Therefore, each device has pros and cons. Supercapacitors usually provide a high power density (i.e., a fast charge/ discharge velocity) due to the fast physical charge-discharge process across the interfaces between electrode materials and the electrolyte solutions, while the energy density is usually small (≈5 Wh kg −1 ). In comparison, batteries often offer a large energy density (i.e., a large specific energy capacity of ≈200 Wh kg −1 ) attributed to the chemical redox reactions which take place throughout the whole volume of electrode materials, while the operation rate is relatively slow. [2] To construct desirable energy storage devices, porous materials have been widely adopted, particularly for electrodes and SSEs. These materials typically feature a large fraction of interconnected or reticulated porosity with a high specific surface area (SSA), offering numerous potential active sites and mass transfer channels. For example, porous materials based on nanocarbons (e.g., carbon nanotubes, graphene), conducting polymers, and conjugated microporous polymers with high electrical conductivity and large SSAs have been frequently adopted for supercapacitors, [3] while porous carbons, MoS 2 , and metal oxides have been used for LIBs because of the theoretically large stoichiometric lithium content in the respectively lithiated compound and an accelerated Li diffusion rate inside the pores. [4][5][6] Despite considerable progress made so far, these porous materials fall short of sufficiently large SSAs and readily tunable pores, which constrain the upper limit for the performance optimization and affect an accurate investigation of the structure-performance relationship.Metal-organic frameworks (MOFs) feature rich chemistry, ordered micro-/ mesoporous structure and uniformly distributed active sites, offering great scope for electrochemical energy storage (EES) applications. Given the particular importance of porosity for charge transport and catalysis, a critical assessment of its design, formation, and engineering is needed for the development and optimization of EES devices. Such efforts can be realized via the design of reticular chemistry, multiscale...

Supercapacitors (SCs), one of the most popular types of energy-storage devices, present lots of advantages, such as large power density and fast charge/discharge capability. Being the promising SCs electrode materials, metal–organic frameworks (MOFs) and their derivatives have gained ever-increasing attention due to their large specific surface area, controllable porous structure and rich diversity. Herein, the recent development of MOFs-based materials and their application in SCs as the electrode are reviewed and summarized. The preparation method, the morphology of the materials and the electrical performance of various MOFs and their derivatives (such as carbon, metal oxide/hydroxide and metal sulfide) are briefly discussed. Most of recent works concentrate on Ni-, Co- and Mn-MOFs and their composites/derivatives. Conclusions and our outlook for the researches are also given, which would be a valuable guideline for the rational design of MOFs materials for SCs in the near future.

It is important to develop new energy storage and conversion technology to mitigate the energy crisis for the sustainable development of human society. In this study, free-standing porous nitrogen-doped carbon fiber (PN-CF) membranes were obtained from the pyrolysis of Zn–MOF-74/polyacrylonitrile (PAN) composite fibers, which were fabricated in situ by an electrospinning technology. The resulting free-standing fibers can be cut into membrane disks and directly used as an anode electrode without the addition of any binder or additive. The PN-CFs showed great reversible capacities of 210 mAh g−1 at a current density of 0.05 A g−1 and excellent cyclic stability of 170.5 mAh g−1 at a current density of 0.2 A g−1 after 600 cycles in sodium ion batteries (SIBs). The improved electrochemical performance of PN-CFs can be attributed to the rich porous structure derived by the incorporation of Zn–MOF-74 and nitrogen doping to promote sodium ion transportation.
