A new German research initiative, RELIBRE, is exploring the use of computed tomography (CT) technology to assess how usage and ageing impact lithium-ion batteries, with the goal of advancing second-life applications.
The project, led by a consortium of industry and academic experts, seeks to analyze correlations between battery wear and usage through advanced imaging and statistical methods.

The RELIBRE project, short for “Re-use of battery cells: CT analysis of lithium-ion batteries to assess function- and safety-critical characteristics for the second life phase,” focuses on understanding the changes that occur within batteries during their first life cycle. By applying CT imaging, researchers aim to non-destructively examine internal changes that influence ageing, enabling a better evaluation of the batteries’ condition for repurposing in less demanding applications.
The initiative addresses a key challenge in extending battery utility. While batteries may no longer meet performance requirements for their original purpose, they can still serve in less critical roles if their ageing processes are well understood.

By assessing capacity reduction and safety-relevant factors, the project aims to optimize second-life applications and ensure safe reuse scenarios.
Diondo GmbH leads the consortium, which is supported by a €140,000 grant from the German Federal Environmental Foundation (DBU). The findings could improve strategies for sustainable battery use and enhance the lifecycle management of lithium-ion cells, contributing to broader environmental goals.
