Technical FAQs 4

What are the elements of a flow battery?

Electrolytes: The two most important elements of a flow battery are the positive and negative electrolytes, typically stored in separate external tanks. These electrolytes are usually in liquid form and contain ions that facilitate the battery’s energy conversion process.

What materials should be considered in redox flow batteries?

Different aspects of materials and components in redox flow batteries should be considered, including redox-active materials (redox potential, solubility, chemical stability), (2,3) ion-conductive membranes (ion conductivity, selectivity), (4) electrodes (carbon materials, microstructure, catalytic effect), and flow field design.

What is a flow battery?

A flow battery is an electrochemical device that converts the chemical energy of the electro-active materials directly to electrical energy, similar to a conventional battery and fuel cell. However, the electro-active materials in a flow battery are stored mostly externally and are introduced into the device only during operation.

What membrane materials are used in flow batteries?

The second scenario analysis focuses on the membrane materials used for the flow batteries. Although Nafion® is commonly used as the membrane material in flow batteries, various alternative membrane materials have also been developed for battery use.
