The information: One of many main corporations providing options to lithium batteries for the grid has simply obtained an almost $400 million mortgage from the US Division of Power. Eos Power makes zinc-halide batteries, which the agency hopes may sooner or later be used to retailer renewable power at a decrease value than is feasible with current lithium-ion batteries.

What they’re fabricated from: Eos’s batteries are primarily made out of zinc, the fourth most produced steel on the planet, and use a water-based electrolyte (the liquid that strikes cost round in a battery) as a substitute of natural solvent. This makes them extra secure than lithium-ion cells, and means they gained’t catch fireplace.

Why it issues: Whereas the price of lithium-ion batteries has plummeted over the previous decade, there’s a rising want for even cheaper choices. The zinc-based expertise Eos hopes to commercialize may retailer electrical energy for hours and even days at low value. Learn the total story.

How water may make safer batteries

Batteries’ electrolytes dictate quite a bit about how they work, in addition to how secure they’re. A rising variety of various battery makers are turning to an attention-grabbing ingredient to make use of of their electrolyte to decrease the chance of them catching fireplace: water.
