Anwendung metallbasierter MOFs in der Energiespeicherung

An der Hochschule Flensburg wird aktuell der HYDRAD-Speicher entwickelt, der sich durch ein veränderliches Massenträgheitsmoment auszeichnet. Im Gegensatz zu traditionellen Schwungradspeichern, die ihre Drehzahl zur Energiespeicherung und -abgabe variieren, bleibt beim HYDRAD-Speicher die Drehzahl konstant.

What is a metal-organic framework (MOF)?

Among these novel materials, metal–organic frameworks (MOFs), a class of porous materials, have gained increasing attention for utilization in energy storage and conversion systems because of ultra-high surface areas, controllable structures, large pore volumes and tunable porosities.

Why are MOFs used in energy storage devices?

MOFs, because of their high porosity, high surface area, tunable pore size, and hence their structure, show great performance in energy storage devices including various kinds of batteries, fuel cells, and supercapacitors. They have excellent choices of tunable organic linkers and metals, which resulted in different nanostructures.

Can MOFs be used in electrolyte membranes?

MOFs maintain large specific surface area and proton conduction, therefore can be utilized in electrolyte membrane. However, MOFs are electrically insulating in nature due to deficient low energy pathway for carrying charge between metal nodes and ligands, which limits their application in FCs' electrodes.

What are MOFs made of?

MOFs are made up of tunable metal ions and organic linkers and have controllable structures and porosity, as well as large pore volumes and high surface areas.

Are MOFs a viable energy insulator?

Furthermore, MOFs are considered prospective contenders for various commercially viable energy-related applications attributable to these outstanding properties. However, MOFs are generally electrical insulators limiting their use in several applications.

Can MOF derivatives be used in energy storage and conversion applications?

In addition to pristine MOFs, MOF derivatives such as porous carbons and nanostructured metal oxides can also exhibit promising performances in energy storage and conversion applications.
