Second-life lithium-ion battery lifetime extension through self-healing strategies (BLESS)

Research Project, 2026 – 2028

The European Green Deal sets an ambitious goal of achieving climate neutrality by 2050, with lithium-ion batteries (LIBs) playing a pivotal role in enabling sustainable transportation and renewable energy integration. However, millions of LIBs are prematurely retired from electric vehicles (EVs) despite retaining up to 80% of their designed capacity, leading to substantial environmental and economic challenges. Leveraging emerging self-healing (SH) techniques that utilize intelligent pulse-based interventions, the EU-funded research project aims to unlock the untapped potential of second-life LIBs.

Specifically, we will enhance the safety, durability, and lifetime of second-life lithium-ion batteries for sustainable energy and transportation applications. The project develops advanced battery monitoring, diagnosis, and adaptive restoration methods by combining battery science, data-driven learning, and optimization techniques. Particular focus is placed on early degradation detection, intelligent operational regulation, and long-term lifetime extension under realistic operating conditions.
