Samenvatting

Li-Sulfur battery has garnered attention due to its high energy density. However, owing to complex chemistry the working
mechanism is still ambiguous and often contradictory among peers. Here we present an experimental investigation of Li-S battery cells
where the behavior of current transient during potentiostatic discharge were studied. It was found that the formation of Li2S is more likely
through electrodeposition rather than chemical deposition. The nucleation and growth rate were measured by assuming a 2D progressive
nucleation and growth. The analysis was performed on cells with different electrolyte amount. It was observed that that at rapid discharge
the rate the growth is limited by mass transfer.
