Periodic Reporting for period 1 - HEALING BAT (advanced sensing, monitoring and self-HEALING mechanisms to self-repair BATteries)

Reporting period: 2023-06-01 to 2024-11-30

Summary of the context and overall objectives of the project

HEALING BAT is an EU project that brings together 10 European research centres, leading universities and innovative companies from 6 different countries to investigate the EU batteries of the future, which will be smart and more sustainable.

Within 4 years, the Horizon Europe project will develop and implement self-healing materials and healing strategies in key battery components, used in the conventional lithium-sulfur (Li-S) battery, and extrapolate the designs and concepts to develop a new class of self-restoring Li-S batteries.

HEALING BAT will also create a toolbox consisting of self-healing materials, battery sensors and bespoke battery management systems (BMS), with the aim of maximising the performance of the developed Li-S battery in terms of quality, reliability and lifetime, as well as avoiding or timely healing occurring damages that could lead to battery degradation.

Work performed from the beginning of the project to the end of the period covered by the report and main results achieved so far

HEALING BAT Project is breaking new ground in battery innovation with sensor-enabled batteries that feature built-in healing mechanisms. These smart cell technologies address the unique challenges posed by next-generation batteries, including new failure modes that demand equally novel solutions. The first thin-film prototype sensors are now complete and ready for integration into a battery pouch cell. Achieving this milestone has been a remarkable team effort, blending diverse expertise to deliver innovation.The sensor development is just one aspect of the broader HEALING BAT Project, which spans a wide range of cutting-edge research areas, including:
- Advanced lithium-sulfur battery development,
- Self-healing technologies,
- Data science,
- Lifecycle analysis

Progress beyond the state of the art and expected potential impact (including the socio-economic impact and the wider societal implications of the project so far)

The 30-micron-thick sensors are set to measure spatially-resolved real-time temperature within a battery pouch cell. Future iterations will integrate additional capabilities, such as thermistors, pressure sensors, and gas sensors.
