SALAMANDER Project

The SALAMANDER Project's Sensor-Integrated Self-Healing Technology for Enhanced Performance and Longevity The SALAMANDER project will develop and integrate embedded sensors and self-healing functionality in Li-ion batteries (LIB) to enhance their quality, reliability, and lifetime. This is achieved by demonstrating “smart” aspects in the battery which analyze indicators of its own degradation and independently respond with external stimuli to trigger on-demand self-healing. To achieve this goal, the project proposes 3 types of sensors with 2 types of self-healing mechanisms to counteract the most threatening and damaging reactions that occur in a typical LIB. On the anode, a resistance sensor array will be printed onto its surface to sense the degree of electrode fracture in the silicon/carbon composite anode. Additionally, a life cycle assessment will be conducted to validate the recyclability of the SALAMANDER battery and quantify how the environmental impact of manufacturing is offset by longer-lasting batteries. Thus, although the project’s technology is anticipated to be disruptive at the cell and BMS levels, its design would remain compatible with existing manufacturing and recycling processes. These outcomes thereby help meet the goal of BATTERY 2030+ for a competitive, sustainable European battery value chain and a more circular economy. Our goals: 1 Increase the quality, reliability and life (QRL) of the battery system by integrating self-healing functionalities at the battery cell level. 2 Demonstrate the proof of concept: coupling sensors and self-healing agents via BMS. Demonstrate the benefit of the innovations brought by SALAMANDER to the global battery safety 3 Contribute to the development of a disruptive battery cell and BMS technologies, to support a competitive and sustainable battery manufacturing industry in Europe. 4 Expand the collaboration and contribute to the BATTERY 2030+ large scale initiative.
