[1] Volume changes and parasitic side reactions with the electrolyte are undesirable ageing effects which can happen during cycling and shorten the lifespan of a battery. The focus of this work is on investigating ageing phenomena like thickness change of the electrode as well as electrolyte degradation.enSodium Ion BatteriesHard CarbonAgingAdvanced CharacterizationDilatometryOperando AnalysisGas ChromatographyMass Spectrometryposter
