Abstract
A method for cycling a lithium-sulphur cell, said method comprising discharging a lithium-sulphur cell, terminating the discharge when the voltage of the cell reaches a threshold discharge voltage that is in the range of 1.5 to 2.1V, charging the lithium-sulphur cell, and terminating the charge when the voltage of the cell reaches a threshold charge voltage that is in the range of 2.3 to 2.4V, wherein the lithium-sulphur cell is not fully charged at the threshold charge voltage, and wherein the lithium-sulphur cell is not fully discharged at the threshold discharge voltage.
