Zinc battery that lasts

Zinc-bromine batteries have existed for decades, inexpensive, durable, and built from abundant materials. So why are they nearly impossible to find on the market? The answer is almost always the same: the bromine inside the battery does not stay put. It migrates, reacts with unwanted species, and shortens the battery's lifespan, until it simply ceases to be economically viable.

Prof. Malachi Noked and Prof. Doron Aurbach of BINA, Bar-Ilan University, approached the problem through a single, deceptively simple question: what if we could learn to keep the bromine in place?

It turns out we can. Bromine can be confined without compromising performance, not through an engineering workaround, but through a deep understanding of the battery's internal chemistry.

And the results? A significant improvement in battery lifespan.

If you work in grid-scale energy storage, this research is worth your attention.
