The Download: promising new batteries, and how to regulate AI

This is today’s edition of The Download our weekday newsletter that provides a daily dose of what’s going on in the world of technology.

Zinc batteries that offer an alternative to lithium just got a big boost

The news: One of the leading companies offering alternatives to lithium batteries for the grid has just received a nearly $400 million loan from the US Department of Energy. Eos Energy makes zinc-halide batteries, which the firm hopes could one day be used to store renewable energy at a lower cost than is possible with existing lithium-ion batteries.

What they’re made of: Eos’s batteries are primarily made from zinc, the fourth most produced metal in the world, and use a water-based electrolyte (the liquid that moves charge around in a battery) instead of organic solvent. This makes them more stable than lithium-ion cells, and means they won’t catch fire.

Why it matters: While the cost of lithium-ion batteries has plummeted over the past decade, there’s a growing need for even cheaper options. The zinc-based technology Eos hopes to commercialize could store electricity for hours or even days at low cost. Read the full story.

How water could make safer batteries

Batteries’ electrolytes dictate a lot about how they work, as well as how safe they are. A growing number of alternative battery makers are turning to an interesting ingredient to use in their electrolyte to lower the risk of them catching fire: water.

How should we regulate AI?

AI is everywhere, but few experts can agree just how it should be regulated. Next week, on September 12, we’re holding the second MIT Technology Review Roundtable: a 30-minute conversation with our writers and editors—and this one’s all about AI.

Melissa Heikkilä, our senior reporter for AI, will be chatting with news editor Charlotte Jee about what should be done to keep AI companies in line. Roundtables are free for MIT Technology Review subscribers, so if you’re not already, what more reason do you need to sign up? Become one today from just $80 a year.
