Abstract Scope |
Understanding degradation and failure of lithium-ion batteries (LIB) is critical for the safe and reliable operation of electric vehicles. Tracking degradation over time is crucial to develop technologies for battery prognostics. Prognostics of LIBs is however challenging due to the interdependence of degradation mechanisms stemming from different electrodes, usage history and operating conditions. Three-electrode (3å) cells offer a convenient operando platform to examine and deconvolute the fundamental reaction mechanisms responsible for electrode degradation under a variety of operational extremes. By employing an array of recently developed data analytics techniques and parameters using the reference electrode measurements, three-electrode cells can be used as an analytics toolbox for identifying the fundamental degradation mechanisms and its observable consequences at the cell level. |
