Second life batteries

Batteries can have a second chance to create sustainable value, enabling a more efficient energy consumption

The case for second life batteries

When batteries reach the end of their ‘automotive’ life cycle, they still have a residual capacity of about 70-80% and can be applied for different usage after their initial lifecycle has come to an end. As part of the solutions for the energy transition, storage and batteries are tools to enable sustainability and, at the same time, they themselves must be fully sustainable. Extending the life of batteries means reducing their carbon footprint and increasing the amount of renewable energy on the grid. Enel X’s efforts are particularly focused on developing new technologies for li-ion solutions batteries and for their application.


Electricity storage systems and batteries play a strategic role in the energy transition value chain, they are essential to realize more effective, efficient, and competitive electrification solutions in several areas. From renewables and smart grids, storage systems and batteries make consumption more efficient for factories and buildings.
