The battery second life value chain is one of the most important frontiers in Europe’s clean energy transition. In April 2026, CIRCUBATT brought its research to the Advanced Battery Manufacturing Workshop in Cambridge — presenting how batteries can generate economic and environmental returns well beyond their first use.
What the workshop was about
The Advanced Battery Manufacturing Workshop is a gathering of researchers, engineers, and industry representatives working on the future of battery technology in Europe. The April 2026 edition took place at Homerton College, Cambridge, and brought together voices from academia, industry, and EU-funded research.
CIRCUBATT was represented by Hetty Sun and Mao Maggie Xu from the University of Greenwich, alongside project coordinator Li Zhou — who supported both the presentation and networking activities.
What CIRCUBATT presented
The presentation made the case for treating batteries as multi-life assets rather than single-use products. A battery that has served its purpose in an electric vehicle, for example, may still hold significant capacity for stationary energy storage — a second life that delays disposal and creates new economic value.
Unlocking that value requires two things working together: sustainable design from the start, and digital intelligence throughout the battery’s life. CIRCUBATT’s approach combines both.
On the design side, the project develops battery cells and packs built for disassembly and repurposing — making second-life transitions technically feasible rather than economically prohibitive. On the digital side, AI-driven lifecycle monitoring tracks battery health in real time, giving operators the data they need to make reliable decisions about reuse, repurposing, or recycling.
Together, these elements support a battery second life value chain that is not just technically possible, but commercially viable.
Why this matters for Europe
Europe’s demand for batteries is growing fast — driven by electric vehicles, renewable energy storage, and the broader electrification of industry. At the same time, the EU Batteries Regulation is raising the bar on what responsible battery management looks like: higher recycled content requirements, mandatory battery passports, and stricter end-of-life obligations.
In this context, building a robust battery second life value chain is not just good environmental practice. It is a strategic necessity. Every battery that is reused or recovered efficiently reduces Europe’s dependence on critical raw materials like lithium, cobalt, and nickel — materials that are costly, scarce, and often sourced from geopolitically sensitive regions.
CIRCUBATT is building the technical and business foundations to make this transition real.
What comes next
The Cambridge workshop was one of several dissemination activities CIRCUBATT has planned for 2026. The project runs until 2027, and the team is actively sharing progress with the wider battery research and industry community.
