PHOENIX
Horizon Europe EU-funded project PHOENIX
Building more reliable and performant batteries
PHOENIX aims to develop battery cells with integrated sensors (mechanical, enhanced impedance spectroscopy, temperature, gas, reference electrode) and self-healing functionalities (magnetically activated polymers, thermally activated polymers, metallic organic frameworks coated separator, core-shell NMC composites).
Tailor made triggering devices to activate self-healing mechanisms will be developed, prototyped and demonstrated in Generation 3b and 4a Li-ion batteries. A Battery Management System (BMS), capable of detecting defective operations and of triggering self-healing functionalities will be developed with in-line communication.
The degradation detection and quality, reliability and life (QRL) will be tested through dedicated profiles (fast charging, extreme temperatures, calendar life). The novel batteries’ manufacturing will be studied from a recycling and mass production point of view.
PHOENIX’s objectives:
- 1. Develop sensors to detect healable degradation mechanisms
- 2. Develop materials with self-healing functionalities triggered by external stimulus to eliminate/avoid failure mechanisms inbattery cell components
- 3. Develop triggering devices to activate self-healing mechanisms
- 4. Demonstrate proof of concept for coupling sensors and self-healing agents via BMS
- 5. Detect critical degradation processes during cell ageing and estimate the QRL over the life span
- 6. Assess the environmental sustainability and demonstrate the competitive advantage over alternative approaches such as replacement, recycling or second use
- 7. Adopt an adaptable approach towards battery cells mass production processes which do not hinder the subsequent recycling process and enables an economic evaluation of the developed cells.
Our tasks in the project
- Synthesis of NMC90 cathode powders with Core/Shell morphology
- Production of MOFs-integrated separators
- Development of Gas Sensors for detection of cell degradation processes
