Porsche Builds New EV Batteries from Old Ones

The batteries powering tomorrow's electric Porsches might come from the ones driving today.

Porsche announced it successfully built prototype battery cells using lithium, nickel, cobalt, and manganese recovered from worn-out high-voltage batteries. The cells are now undergoing rigorous testing to see if they match the performance and durability standards needed for future production vehicles.

The automaker launched this recycling project last year with German company cylib, aiming to create a closed-loop system. Instead of mining fresh materials from the earth, they're pulling valuable metals from end-of-life battery packs and transforming them into new cathode material.

Here's how it works: Porsche Centers across Germany collect old battery packs and send them for recycling. The batteries get discharged, dismantled, and mechanically shredded into something called "black mass," a powder containing all those precious battery materials. Then specialists separate and refine those materials until they're ready to go back into new batteries.

Since May, batteries have been flowing into the program. Porsche expects the recovered materials to become available for broader battery production starting in 2028.

"We have achieved an important technological milestone," said Joachim Scharnagl, Porsche's executive board member for procurement. "This innovation is a key step in advancing both circular economy principles and raw material resilience."

The Ripple Effect

This breakthrough matters beyond Porsche's bottom line. As electric vehicles continue growing in popularity, demand for lithium, nickel, and cobalt is expected to surge. Recycled materials could supplement future supplies while reducing the environmental impact of mining operations.

More automakers are now building their own closed-loop systems rather than relying on third parties to handle recycling. This shift means recovered materials flow directly back into their own supply chains, creating a more sustainable and secure future for electric vehicle production.

The water-based recycling process developed by cylib offers another advantage over traditional methods. It's designed to be more environmentally friendly while still recovering battery-grade materials suitable for manufacturing.

Initial testing suggests the concept works technically. Porsche expects comprehensive results later this year that will confirm whether recycled cathode materials perform as well as those made from newly mined minerals.

If successful, this technology could reduce both the environmental footprint of battery manufacturing and protect automakers from volatile global raw material markets.

The future of electric vehicles might just be circular.
