Don’t Hold the Salt
How better chemistry is solving the EV battery materials shortage
Ric Edelman: It's Wednesday, November 29th. I mentioned yesterday that Global X had launched one of the industry's first thematic ETFs, the Global X Lithium and Battery Technology ETF. The symbol is LIT. Why did they bother doing that? Well lithium is key to lithium ion batteries. That's how we have electric vehicles and wind turbines and solar panels. But lithium is scarce and that means expensive. So some companies are trying to come up with an alternative to making batteries with lithium.
And guess what they're looking at? Sodium. Yeah, table salt. Sodium, to put it mildly, is abundant. It makes up most of the salt and all the oceans. And if you layer oxide cathodes with sodium instead of lithium, you really don't need cobalt or nickel to improve performance. So you not only avoid lithium, you also can avoid those minerals which are just as rare and just as expensive. Lithium and sodium are called alkali metals. If you play around the sodium, you come up with compounds like sodium chloride, table salt. But if you tinker in a different way, you create a new set of atoms that make an electrochemical cell, and you can draw energy from it.
The bottom line is that sodium can provide electricity just like lithium. So why are we using all this lithium in the first place? It's because sodium atoms are a lot bigger and heavier than lithium atoms. So you can forget about using sodium to power your car or your phone, but it sure can be an alternative for powering your house or a ship. Who cares how heavy the power generator is for those uses?
And as we've seen in so many areas, a lot of the research is going on in China. Three dozen Chinese companies are developing this tech, threatening America's leadership in this field. But there are US companies, too, including Natron Energy in California and others around the world like Altris in Sweden. Lithium is a big deal, and it will likely remain a big deal for many years to come, which is why the Global X Lithium and Battery Technology ETF is worth considering. But soon you'll be able to buy an ETF that invests in table salt. Pass the ketchup while you're at it.
