Organic framework materials for energy storage

What are metal-organic frameworks?

Of particular interest, metal–organic frameworks (MOFs) have emerged as promising platforms to develop advanced materials for efficient ECS systems. (2,6−8) Compared with conventional materials, MOFs offer various unique compositional and structural advantages by virtue of the highly ordered and tunable metal nodes and organic linkers ( Figure 1 ).

What is a metal-organic framework (MOF)?

Metal–organic frameworks (MOFs) have emerged as desirable cross-functional platforms for electrochemical and photochemical energy conversion and storage (ECS) systems owing to their highly ordered and tunable compositions and structures.

What is a promising application of metal-organic frameworks?

Metal-organic frameworks (MOFs) are a new promising class of materials for a high performance supercapacitor electrode. Yang, J., Xiong, P., Zheng, C., Qiu, H. & Wei, M. Metal-organic frameworks: a new promising class of materials for a high performance supercapacitor electrode. J. Mater. Chem. A 2, 16640–16644 (2014).

What is a covalent organic framework?

Covalent organic frameworks (COFs) are a class of porous crystalline materials based on reticular and dynamic covalent chemistry. Flexible molecular design strategies, tunable porosity, modifiable frameworks, and atomically precise structures have made them powerful platforms for developing advanced devices in energy storage and conversion.

Are Metal-organic frameworks (MOFs) conductive?

Although most MOFs are not electronically conductive, framework-localized redox reactions have been accomplished using conductive additives. Such composites are multifunctional by combining the high-surface area and chemical tunability of MOFs with the conductivity of polymers and carbon materials.

Should amorphous MOF materials be used in electrochemical energy storage devices?

While MOFs have shown promise in electrochemical energy storage devices, amorphous MOF materials may not be the best choice. They excel in electronic applications requiring enhanced flexibility, transparency, and high charge mobility. Our review highlights strategies for employing MOFs in electrochemical energy storage devices.
