Redwood Materials, Proterra partner to recycle EV batteries

Recycling startup Redwood Materials is partnering with electric vehicle manufacturer Proterra to recycle and repurpose EV battery materials.

Despite being designed to last the lifespan of the vehicle, Proterra offers a battery leasing program that guarantees replacement after six years. With as much as 80-90 per cent charging capacity remaining in the battery, Proterra re-uses the batteries in second-life applications including stationary storage systems connected to Proterra’s charging hardware.

Once the battery life is exhausted, the end-of-life batteries will be sent to Redwood’s facility in Nevada, where the waste will be reprocessed into valuable raw material.

“First, the grading of the battery will occur at Proterra by our remanufacturing engineering team. If the battery is deemed ready for a second life, it will go into one of those applications; If it’s not, it gets recycled,” Proterra Chief Technology Officer, Dustin Grace told TechCrunch.

“It’s still early days but we’re trying to set ourselves up for the future state of this market at scale. That’s really the primary benefit of this partnership existing today.”

Since entering the partnership, Proterra has sent around 26,000 pounds of battery material, however, this does not represent the pace of future deliveries. Overall, Redwood receives 60 tons per day or 20,000 tons of batteries per year.

“The way we see it, domestic cell production for Proterra is a very, very important part of the roadmap here in the coming years. The idea of generating more battery-grade raw materials on North American soil directly supports the expansion of the battery manufacturing concept within the U.S. So I think this starting now absolutely aids out plans for domestic cell manufacturing in the near future.”

Redwood Materials has quickly expanded since its launch in 2017 by Tesla co-founder JB Straubel to become the largest lithium-ion battery recycler in Northern America. Redwood already has arrangements with Panasonic, Amazon and e-bike manufacturer Specialized to recycle their EV batteries and other waste.

Redwood aims to create a circular battery supply chain through these business-to-business partnerships.
