Heterogenic Aging in Large Intercalation Batteries (HALIBatt-KTH)
Research Project, 2022 – 2026

The goal of this project is to quantify, explain, and describe the uneven distribution of cell ageing observed in various large cells with different chemistries. In particular, Lithium plating seems to occur unexpectedly in some parts of the cells. The broadness of the scope of the project requires the establishment of a consortium of several SEC sub-projects, in addition to two industrial doctoral projects. This to i) include cycling of new cell types on the market containing silicon graphite composites, sodium ions and batteries for battery electric vehicles or for hybrid operation with fuel cells. Further, to ii) develop post-mortem analyses including electrochemical characterisation, comprehensive analysis of the electrode materials, electrolyte, interfaces, and Lithium plating. To test hypotheses, iii) conduct targeted studies with lab cells under controlled conditions (temperature and pressure) and investigate how sensors can be used to detect ageing and plating in operation. For evaluation of data, iv) develop new modelling tolls where the old fails. A further purpose is that the models should contribute to the battery management system (BMS).
