Something like 80% of the used lithium-ion batteries in the country go to Redwood Materials for recycling. So they had a thought: what if we hook all these used batteries up as grid-scale storage until they're completely tapped out, and *then* recycle them? Thus was born: Redwood Energy.
Can "second life" EV batteries work as grid-scale energy storage?
Colin Campbell explains how Redwood drains every drop of capacity from used batteries before they are recycled.

Today on Volts: Redwood Materials, the biggest battery recycler in the US, has launched Redwood Energy, which will gather used batteries & hook them up to power banks to serve as grid-scale storage until they're depleted. I talk with the CTO about the logistics & potential of second-life batteries.
