“…The qualitative analysis of the main signals is consistent with previous works in which the LiCoO 2 was obtained in a single phase and exhibited bands attributed to oxygen vibrations involving mainly Co-O stretching (A 1 g ) and O-Co-O bending (E g ) vibrations [39,40]. The spectrum lacks the so-called defect band (D band), related to C-C stretching modes related with graphite or carbonaceous species [41].…”

Lithium cobalt oxide (LiCoO2) is one of the most relevant components in lithium-ion batteries. The array of sought-after features of LiCoO2 depends on its synthesis method. In this work we synthesized and characterized a nanocrystalline LiCoO2 oxide obtained with a wet chemistry synthesis method. The oxide obtained was a homogeneous powder in the nanometric range (5-8 nm) and exhibited a series of improved properties. Characterization by FTIR and UV-Vis techniques led to identifying citrate species as main products in the ﬁrst step of the synthesis process. X-ray diffraction (XRD), Raman, and transmission electron microscopy (TEM) characterizations led to identifying a pure crystalline phase of the synthesized LiCoO2 oxide. Steady state electrical characterization and solid-state impedance spectroscopy determined the high conductance of the synthesized oxide. All these features are desirable in the design of cathodes for lithium ion batteries.

“…As a proof of concept, Lin et al recently reported a binder-free LiCoO 2 cathode by pyrolysis of Li-doped ZIF-67. 50 SIBs. With the increasing concerns of the cost and limited lithium reserve, SIBs that possess a similar working mechanism to LIBs have received much interest as a promising alternative to LIBs for grid-scale energy storage.…”

View full text Add to dashboard Cite

With many apparent advantages including high surface area, tunable pore sizes and topologies, and diverse periodic organic−inorganic ingredients, metal−organic frameworks (MOFs) have been identified as versatile precursors or sacrificial templates for preparing functional materials as advanced electrodes or high-efficiency catalysts for electrochemical energy storage and conversion (EESC). In this Mini Review, we first briefly summarize the material design strategies to show the rich possibilities of the chemical compositions and physical structures of MOFs derivatives. We next highlight the latest advances focusing on the composition/structure/performance relationship and discuss their practical applications in various EESC systems, such as supercapacitors, rechargeable batteries, fuel cells, water electrolyzers, and carbon dioxide/nitrogen reduction reactions. Finally, we provide some of our own insights into the major challenges and prospective solutions of MOF-derived functional materials for EESC, hoping to shed some light on the future development of this highly exciting field.

world's energy system from non-renewable fossil energy to low-carbon and multienergy fusion. How to fully develop and efficiently utilize clean energy to achieve carbon emission reduction has become a common concern of all countries around the world. In recent years, highly efficient electrochemical energy storage devices have attracted more attention and significantly impacted on scientific and industrial communities. [1] They can execute intermittent power storage and release, unrestricted by the geographical terrain, and can be directly applied to practical demands, such as electric vehicles, large-scale energy storage, and micro-devices. Currently, hundreds of electrochemical energy storage devices have been developed, exhibiting different technical mechanisms and application spaces. [2] Supercapacitors dominate the field of high power applications, while rechargeable metal-ion batteries such as lithium-ion batteries (LIBs) and next-generation metal-ion batteries (low-cost and abundant potassium, sodium, magnesium, zinc, and aluminum battery systems) are expected to govern high energy density applications. [3][4][5] During the discharge process, positive ions migrate from the anode into the cathode and generate electrons, while the charging process is the opposite. [6] During this reversible process, electrode materials are the core components in metal-ion batteries and the main substances in an electrochemical redox reaction and their physical and chemical properties closely correspond to the performance of electrochemical energy storage equipment in either electrolytic or galvanic cell systems. Therefore, developing novel, highly active, multifunctional electrode materials has become a key issue in achieving efficient energy storage and conversion. [7] Currently, cathode materials occupy the most important position in the composition of metal-ion batteries. [8] The properties of cathode materials directly determine the final performance indexes of metal-ion battery products. [9] Moreover, in commercial LIB devices, cathode materials account for about 40% of the cost of the whole cell. [10] However, compared with the fast-developing development of anode materials, the development of cathode materials has been relatively slow. One reason is that it is challenging to prepare highly crystalline cathodes, and even slight changes in the preparation process can lead to great differences in material structures and properties. Another factor is that cathode materials present a low specific capacity relative to anode materials, which directly influences the energy density Metal-organic frameworks (MOFs) and covalent-organic frameworks (COFs) are two emerging families of functional materials used in many fields. Advantages of both include compositional designability, structural diversity, and high porosity, which offer immense possibilities in the search for high-performance electrode materials for metal-ion batteries. A large number of MOF/COF-based cathode materials have been reported. Despite these advantageous fea...
