What Are Second-Life Batteries and Why Are They Key to Europe’s Energy Future?

What Are Second-Life Batteries and Why Are They Key to Europe’s Energy Future?

News

As Europe takes bold steps toward climate neutrality and energy independence, the focus on sustainable battery solutions has never been more urgent. Among the most promising innovations? Second-Life Batteries (SLBs).

But what exactly are SLBs and why do they matter?

A Second Life with a Powerful Purpose

After a battery has completed its first life in an electric vehicle (EV), it typically retains 70–80% of its original capacity. While no longer suitable for EV performance, these batteries still have immense potential in stationary energy storage applications. That’s where Second-Life Batteries come into play.

By repurposing these batteries instead of recycling them immediately, SLBs offer a cost-effective and environmentally friendly way to support:

  1. – Grid flexibility
  2. – Residential or commercial energy storage
  3. – Renewable energy integration
  4. – Charging infrastructure for EVs

Circular Economy in Action

SLBs are a cornerstone of the circular economy model, extending battery lifecycles, reducing electronic waste, and making better use of raw materials. They also offer a way to decrease the carbon footprint and economic cost associated with manufacturing new batteries.

In short: SLBs are not just a technical innovation, they are a systemic shift in how we produce, use, and reuse energy technologies.

Enter the BIG LEAP Project

While the potential of SLBs is huge, challenges remain. Safety, performance, and predictability must be guaranteed before these batteries can be deployed at scale.

This is where the BIG LEAP project steps in.

Co-funded by Horizon Europe, BIG LEAP is working to optimize the performance, safety, and reliability of SLBsthrough the development of a three-level Battery Management System (BMS). This unique approach enhances control, monitoring, and predictive capabilities, ensuring SLBs can operate effectively in real-world conditions.

BIG LEAP also aims to:

  • – Boost the interoperability of Battery Management Systems
  • – Validate second-life use cases in real applications
  • – Strengthen the circular value chain of batteries in Europe

Smart, Sustainable, and Scalable

By developing smart and modular solutions for SLB deployment, BIG LEAP supports Europe’s transition to a clean, secure, and affordable energy future. Whether it’s supporting grid resilience, integrating renewables, or powering off-grid systems, SLBs will play a central role in Europe’s energy ecosystem in the years ahead.

Rebelion 

REBELION is a project funded by the European Union with the objective of addressing the waste management challenges posed by lithium-ion batteries (LIBs) used in electric mobility. After their second life, recycling represents not only the most environmentally friendly alternative for batteries, but also a natural and economic resource since the raw materials contained in LIBs can be valorised for further manufacturing. This is particularly relevant in the EU, which is a net importer of critical raw materials while up to 40% of the EVs are sold in Europe. Therefore, a solid recycling industry can become the European mining equivalent, promoting both environmental and economic benefits to the EU region.

TradeRES 

The TradeRES project will develop and test innovative electricity market designs that can meet society’s needs of a (near) 100% renewable power system. A long-term sustainable market design needs to provide efficient operational and investment incentives for an electricity system that is characterized by a high share of variable renewable energy sources (VREs) by increasing integration with other energy sectors, e.g. transport and hydrogen, and by increasing participation of flexible electricity demand from households to industrial consumers. Furthermore, this market design needs to provide security of supply by ensuring sufficient controllable electricity generation capacity whilst being economically efficient. Finally, despite the variability of solar and wind energy, the market risks should be allocated in an efficient and socially accepted way. This should also safeguard that consumers are not exposed to extreme swings in their energy expenses. In this sense, this project aims at finding market designs that are economically efficient in the above setting. To achieve these goals the project will use an iterative methodology and involve the key players from the energy sector in order to achieve and test the most suitable market designs. The project TradeRES – Tools for the Design and Modelling of New Markets and Negotiation Mechanisms for a ~100% Renewable European Power System, is funded by the EU framework programme for research and innovation Horizon 2020 under the call H2020-LC-SC3-2019-ES-SCC.
