“…However, MOFs-based electrodes with other kinds of organic linkers are seldom employed in LIBs for the lack of highly-active lithiation sites. Regarding to ZIFs, although they have been intensively used as sacrificial templates or cladding materials to develop carbon [20,21], ZnO [22], Sn/C [23] or thin film [24] for LIBs, their direct application as highperformance lithium storage electrode materials is still challenging. Tang et al [25] recently reported the use of thin-film ZIF-8 and ZIF-67 electrodes as anodes for LIBs.…”

In this work, a bimetallic zeolitic imidazolate framework (ZIF) CoZn-ZIF was synthesized via a facile solvothermal approach and applied in lithium-ion batteries. The as-prepared CoZn-ZIF shows a high reversible capacity of 605.8 mA h g −1 at a current density of 100 mA g −1 , far beyond the performance of the corresponding monometallic Co-ZIF-67 and Zn-ZIF-8. Ex-situ synchrotron soft X-ray absorption spectroscopy, X-ray diffraction, and electron paramagnetic resonance techniques were employed to explore the Li-storage mechanism. The superior performance of CoZn-ZIF over Co-ZIF-67 and Zn-ZIF-8 could be mainly attributed to lithiation and delithiation of nitrogen atoms, accompanied by the breakage and recoordination of metal nitrogen bond. Morever, a few metal nitrogen bonds without recoordination will lead to the amorphization of CoZn-ZIF and the formation of few nitrogen radicals.

“…MOFs like ZIF‐8[139,155] and ZIF‐67 have been widely studied to get N‐doped carbon with micropore dominant structure. [139,155,156] This indeed restricts the reaction kinetics by limiting the mass transport and the use of active sites in ORR. Therefore, special attention has given to the carbonization techniques.…”

Exploring new materials with high efficiency and durability is the major requirement in the field of sustainable energy conversion and storage systems. Numerous techniques have been developed in last three decades to enhance the efficiency of the catalyst systems, control over the composition, structure, surface area, pore size, and moreover morphology of the particles. In this respect, metal organic framework (MOF) derived catalysts are emerged as the finest materials with tunable properties and activities for the energy conversion and storage. Recently, several nano- or microstructures of metal oxides, chalcogenides, phosphides, nitrides, carbides, alloys, carbon materials, or their hybrids are explored for the electrochemical energy conversion like oxygen evolution, hydrogen evolution, oxygen reduction, or battery materials. Interest on the efficient energy storage system is also growing looking at the practical applications. Though, several reviews are available on the synthesis and application of MOF and MOF derived materials, their applications for the electrochemical energy conversion and storage is totally a new field of research and developed recently. This review focuses on the systematic design of the materials from MOF and control over their inherent properties to enhance the electrochemical performances.

“…with smaller particle sizes are deduced to have much faster diffusion rate than CO/ZCO (1.3mmol, 12h, 10). The nanosizing particle shortens the diffusion pathway and provides abundant channels for electrolyte penetration thus has faster diffusion and larger capacitance at high frequency [1,[69][70][71], as shown in Figure 8c. They display a specific capacity of 890 mAh g -1 at a current rate of 0.1 A g -1 and…”

Binary metal oxides offer improved anode materials in lithium ion batteries owing to enhanced electrical conductivity but suffer from large volume expansion on lithiation. A novel route to hollow Co3O4 nanospheres doped with ZnCo2O4 is demonstrated that mitigates the expansion issue and shows excellent performance at high current densities. The synthetic route is based on the pyrolysis of binary metalorganic-frameworks (MOFs) with the controlled loss of zinc tuning the micro and nanostructure of the material through a thermal vapor mechanism. The optimal structures, that contain hollow Co3O4 spheres of ca. 50 nm diameter doped with ZnCo2O4, show a specific capacity of 890 mAh g-1 at a current rate of 0.1 A g-1 and show a similar specific capacity at 1 A g-1 after 120 cycles at high current densities. The kinetics of lithiation/delithiation changes from diffusion-controlled to a surface-controlled process by the nanosizing of the particles. The resultant faster ion diffusion and capacitive storage for lithium ions are responsible for the extraordinary high-rate performance of the hollow structures.
