On degradation mechanism of lithium-sulfur batteries

Using the method of normalized galvanostatic curves, as well as taking into account the changes in the half-charge and half-discharge potentials of an electrode, the latter based on a sulfur composite with reduced graphene oxide, it was established that the main reason for electrode degradation during cycling was the loss of active material (due to the shuttle transfer of polysulfides and sulfur from the positive electrode to the negative lithium one).
