Lithium-ion batteries are in almost all electronics, all electric vehicles and are expanding through the power grids worldwide to store energy during system outages. They are crucial to continued operation of “green” data centers. When you talk about renewable energy, you have to talk about where lithium-ion batteries fit in the discussion.

That’s not necessarily a good thing.

Lithium-ion technology is fraught with social, environmental, and security downsides. Forced child labor, the lack of effective recyclability, potential poisonous fires and explosions and complex, imminently hackable control systems are all aspects of the industry that just won’t be going away soon. But there is hope. There are alternatives.

This is the subject of this episode of Crucial Tech. We talk to Jack Pouchet, Vice President of marketing for Natron Energy, a company manufacturing a sodium-ion battery that lacks all the downsides of its lithium cousin and offers significant upsides that we need. The good news is that it looks like this technology will be going into large-scale production just before the Lithium-ion technology collapses under its own weight.
