Title: Method for forming sulfur-containing electrode using salt additive

Abstract

The present disclosure relates to sulfur-containing electrodes and methods for forming the same. For example, the method may include disposing an electroactive material on or near a current collector to form an electroactive material layer having a first porosity and applying pressure and heat to the electroactive material layer so that the electroactive material layer has a second porosity. The first porosity is greater than the second porosity. The electroactive material may include a plurality of electroactive material particles and one or more salt additives. The method may further include contacting the electroactive material layer and an electrolyte such that the electrolyte dissolves the plurality of one or more salt particles so that the electroactive material layer has a third porosity. The third porosity may be greater than the second porosity and less than the first porosity.
