Contemporary Amperex Technology or CATL recently unveiled their first generation sodium ion batteries for commercial use. I have been hearing a lot about this technology and thought that it would be worth talking about.

Scientists started off developing sodium ion batteries right alongside lithium ion batteries. Over time, lithium rose to dominance and sodium fell by the wayside. But now things have changed, and sodium ion batteries have started to see renewed interest. 

In this video, we will briefly review sodium ion batteries, their state of development, and what their commercialization means for the renewable energy market at large.
