The Importance of Testing for the Second Life of Lithium-Ion Batteries

Lithium-ion batteries play a crucial role in electromobility and stationary energy storage.

After their primary use, many of these batteries remain functional and can be repurposed in a "second life." Reusing them offers numerous ecological and economic benefits, including reduced resource consumption, lower CO₂ emissions, and an extended lifecycle for valuable materials.

However, the quality and safety of used batteries vary significantly, as their condition depends on previous usage and stress factors. Comprehensive testing is therefore essential to assess their remaining capacity, performance, and safety. Systematic testing procedures help identify defective or unsuitable batteries early, ensuring a reliable second-life application.

The implementation of standardized testing methods for second-life batteries is key to increasing their acceptance and economic viability. It paves the way for more sustainable energy solutions and optimized resource utilization in an increasingly electrified world.

Temperature and climatic chambers are playing a crucial role in the field of second life battery analysis and validation. Hendrik Andersen, researcher at the Southern Danish University will illustrate this importancy during the webinar.
