The Change of the Lithium-Sulfur Cell Components Properties by its Cycling
The changes to properties of lithium-sulphur cell components (electrolyte, sulphur and lithium electrodes) during cycling were studied by AC impedance spectroscopy. It was found that the changes to properties of these components vary depending on the state of charge. We believe that observed changes...

| Zusammenfassung: | The changes to properties of lithium-sulphur cell components (electrolyte, sulphur and lithium electrodes) during cycling were studied by AC impedance spectroscopy. It was found that the changes to properties of these components vary depending on the state of charge. We believe that observed changes can be explained by formation of soluble lithium polysulfides and by the change of their concentration and composition during the cell cycling. |
