Second life batteries: Enabling sustainability for electric mobility - WHITE PAPER RELEASE

April 9, 2021

As the movement for electric mobility accelerates, the issue of dealing with an increasing stockpile of used EV batteries is becoming urgent, from both an environmental and economic perspective. The optimization of batteries’ life cycle is essential to ensure a sustainable future for electric mobility. 



When an EV battery reaches the end of its useful first life, manufacturers have the options of simply disposing of them, recycling them to recover highly valued metals, or reuse them in stationery applications where reduced performances capabilities are still valuable, through the repurposing or refurbishing of battery packs. This last option where batteries’ life cycle is extended before being recycled is what is meant by “second life batteries”. 

Synergies between utilities and the EV sector must be developed in order to achieve a sustainable and circular life cycle for EV batteries. Moving in that direction, GSEP's Technological Community on Storage have produced a white paper sharing experiences and presenting enabling factors and limits to the integration of second life batteries.
