Illinois researchers explore ‘self-healing’ for energy storage batteries

Read the full story from Midwest Energy News.

Batteries — whether they’re powering a smartphone or storing energy on the grid — take a beating.

Repeated charging and discharging causes all kinds of wear and tear on the devices we increasingly rely on to keep our gadgets, cars and renewable energy sources running. But what if batteries could repair themselves automatically and fix on-the-fly the cracks that lead to dead laptop batteries, the limited range of electric carsand other modern woes?

That’s the idea behind the work of a team led by two professors at the University of Illinois Urbana-Champaign (UIUC). They’re taking self-healing materials research and applying it to a novel subject area: energy storage. The hope is that a better understanding of how nanoparticles bind and come undone will lead to more reliable, longer-lasting and higher-capacity batteries.
