HealingBat – Advanced sensing, monitoring and self-healing mechanisms to self-repair batteries

  • Energy storage

On 1-2 June 2023 the Horizon Europe project “HealingBat” kicks off with a meeting at TU Dortmund. The project is coordinated by the host and includes a total of 10 partners from six European countries: Center for Process Innovation (UK), Coventry University (UK), Helmholtz-Zentrum Berlin für Materialien und Energie GmbH (DE), TU Delft (NL), Paul Scherrer Institute (CH), IDNEO (ES), Fundació Institut de Recerca en Energia de Catalunya (ES), FI Group (PT), SUPRAPOLIX (NL) with the aim to investigate the next generation of battery technologies. HealingBat will be part of the European large-scale research initiative Battery 2030+.

Europe must re-emerge as a world leader in the field of batteries by speeding up the development of underlying critical technologies, enabling a European battery cell manufacturing industry making use of sustainable energy and implementing concepts of the Circular Economy. Today, lithium-ion (Li-ion) chemistries dominate the market for rechargeable batteries, but the current generation is nearing the end of their improvement limits. Li-ion battery performance and manufacturing are unlikely to keep up improvements at a rate that is sufficient to establish a climate-neutral society without substantial breakthroughs. Consequently, innovative ideas are needed to allow for the development of future sustainable batteries, which demand less resources and create the groundwork for EU competitiveness.

HEALINGBAT aims at developing and implementing self-healing concepts and materials in the key battery components, used in conventional Li-S batteries and extrapolate the designs and concepts to develop a new class of self-healing structural battery based on Li-S. Healing bat will develop a toolbox, consisting of self-healing materials, relevant sensors and bespoke battery management systems to maximize performance of the developed Li-S battery in terms of the quality, reliability and lifetime and avoid or timely heal occurring damages. The purpose of is to control the flow of energy to and from the battery system, monitor for errors and to apply corrective actions, where necessary.
