The Second Life of America’s EV Batteries

Recycling firm and energy developer join forces to turn retired EV packs into grid-scale storage

5 Nov 2025

A new partnership between a battery recycling company and an energy storage developer aims to turn used electric vehicle batteries into large-scale power systems, addressing the challenge of managing growing volumes of retired EV cells in the US.

The collaboration will repurpose thousands of used lithium-ion batteries into stationary storage units capable of supporting microgrids, data centres and emergency power systems. The partners recently launched a pilot project using repurposed EV packs to stabilise grids and provide backup during blackouts.

The initiative arrives as recycling facilities struggle to process the increasing flow of spent batteries from electric vehicles. Reusing those packs, rather than dismantling them, can extend their lifespan and ease pressure on material supply chains. “Every battery deserves a second life,” said a senior executive involved in the project. “By reusing these packs, we’re saving materials and building a smarter, cleaner grid.”

Analysts see the effort as evidence of a broader shift towards a circular battery economy, where recycling, reuse and renewable energy converge. The model could turn end-of-life management from a cost into a source of value, aligning with federal incentives for domestic recycling and sustainable manufacturing under recent clean energy legislation.

Still, challenges persist. Testing and certifying used batteries for safety and reliability remains complex, while scaling such systems will require new investment and regulatory clarity. Industry experts say policy support will be critical if second-life storage is to move beyond pilot projects.

If successful, the initiative could help the US develop a network of circular energy assets, strengthening grid resilience while reducing waste from the fast-expanding EV market. Details of the partnership’s financial terms were not disclosed.
