Abstract
Methods and apparatus are provided for discharging a Li—S battery having at least one battery unit comprising a lithium-containing anode and a sulfur-containing cathode with an electrolyte layer there between. One method comprises electrochemically surface treating the sulfur-containing cathode during discharge of the battery. A method of electrochemically surface treating a cathode of a lithium-sulfide battery comprises applying at least one oxidative voltage pulse during a pulse application period while the lithium-sulfur battery discharges and controlling pulse characteristics during the pulse application period, the pulse characteristics configured to affect a morphology of lithium sulfide forming on the sulfur-containing cathode during discharge.
