Method for applying a functional compound on sulfur particles

A method for applying a functional compound on sulfur particles, the method comprising:

• (i) supplying to one or more of:
• an atmospheric pressure plasma discharge comprising a gas, and
• an activated gas flow resulting from the atmospheric pressure plasma discharge,
• one or more of:
• a feed comprising sulfur particles, and
• a coating composition,
• (ii) contacting the sulfur particles and the coating composition, wherein the coating composition is converted into the functional compound, wherein the coating composition and/or the functional compound is applied to the sulfur particles;
• wherein the coating composition comprises at least one compound selected from the group consisting of:
• an inorganic electrically conductive compound, an electrically conductive carbon compound, an organic precursor compound of a conjugated polymer, and a hybrid organic-inorganic compound;
• and
• wherein the functional compound provides the sulfur particles with an electrically conductive surface.
