PHOENIX aims to develop battery cells with integrated different sensors (mechanical, enhanced impedance spectroscopy, temperature, gas and reference electrode), and self-healing functionalities (magnetically activated polymers, thermally activated polymers, metallic organic frameworks coated separator, and core-shell NMC composites). To make this possible, tailor-made triggering (magnetic, temperature and pressure) devices to activate self-healing mechanisms will be developed.
The implemented sensors, triggering devices and self-healing properties will be prototyped and demonstrated in different Generation 3b and 4a Li Ion batteries. A universal BMS, being capable to detect defective operation and to trigger self-repairing functionalities will be developed with in-line communication. Additionally, the manufacturing of the novel batteries will be deeply studied from a recycling and mass production point of view. The degradation detection and Quality, Reliability and Life (QRL) will be tested through development of dedicated profiles where not only fast charging, but also extreme temperatures and calendar life will be analysed.
