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.

Are ionically conductive MOFs the future of energy storage?

Ionically conductive MOFs are predicted to see tremendous research activity due to the mounting demand for solid–electrolyte materials in energy storage devices. While proton conductivity in MOFs has been extensively studied, ionically conductive MOFs are expected to gain significant attention.

Can MOF derivatives be used in electrocatalysis and energy storage devices?

MOF derivatives have shown great potential in electrocatalysis and energy storage devices. Herein, we will discuss how unique design strategies of MOFs can be employed to impart select materials functionalities for advancing both performance and fundamental understanding in energy storage devices (Fig. 1).

What are MOF properties in energy storage devices?

Metal-organic frameworks (MOFs) have unique properties that can be leveraged for energy storage devices. a) In metal-ion batteries, MOFs rely on host–guest interactions to store ions and can improve charge conduction by installing electron reservoirs, increasing deliverable capacity. b) In lithium-sulfur batteries, MOFs use host–guest interactions to store lithium and sulfide ions.

How do 2D C-MOFs achieve electrochemical properties?

In the case of coordination frameworks, the redox of the π-d conjugated states contributed by π-electronic states (ligands) conjugating with the d-electrons (M) determines multielectron transfer (Fig. 1a), thus desirable electrochemical properties of 2D c-MOFs can be achieved by designing the electronic structure.

How can MOFs improve charge conduction in metal-ion batteries?

Unique MOF properties for targeting specific challenges in energy storage devices. a Metal-ion batteries rely on host–guest interactions to store ions while installation of electron reservoirs can improve charge conduction and increase deliverable capacity. b Lithium-sulfur batteries use host–guest interactions to store lithium and sulfide ions.
