Redox flow batteries are potentially cheaper, more durable and safer than traditional lithiumion batteries however still require further research and development in order for them to scale. Here, we explore the motivation for flow batteries, discuss how they work, the different components, chemistries and compare them.

00:00 Introduction
00:08 A changing global electricity mix
00:22 Integration of intermittent renewables
01:10 What are redox flow batteries?
02:34 Lithiumion vs flow batteries
03:42 How does a flow battery work?
04:43 Key components of a flow battery
06:06 Flow battery technologies
07:46 Allvanadium flow battery
09:15 Vanadium production
10:18 Zincbromine flow batteries
11:39 IronChromium flow battery
12:53 Comparison of flow battery chemistries
13:51 Conclusions

* Note the diagram for the IronChromium flow battery in slide 12 should have the anolyte and catholyte the other way around.
