摘要: The impact of the formation an electrolyte based decomposition layer on distribution active grain kinetics has been investigated operando within a cycling electrode for lithium battery. It is demonstrated, from fitting procedure electrochemical responses and XRD experiments, that as passive film forms, slow reacting grains appear working operate simultaneously with faster grains. Slow are macroscopically distributed, presumably at side electrode. Discrimination response pertaining to each type allows rationalizing their contribution capacity fading dynamics.
