What are redox flow batteries and why are they important?

Interested in learning more?
Here are some books which I recommend to learn more about the history of batteries and how they've impacted the world
📚 Volt Rush: The Winners and Losers in the Race to Go Green - Henry Sanderson - https://amzn.to/4cJ8lB2
📚 The Powerhouse: America, China, and the Great Battery War - Steve LeVine - https://amzn.to/4bqwRWx
📚 Climate Capitalism: Winning the Global Race to Zero Emissions - Akshat Rathi - https://amzn.to/3xEjmEK

Redox flow batteries are potentially cheaper, more durable and safer than traditional lithium-ion 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 Lithium-ion 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 All-vanadium flow battery
09:15 Vanadium production
10:18 Zinc-bromine flow batteries
11:39 Iron-Chromium flow battery
12:53 Comparison of flow battery chemistries
13:51 Conclusions

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