1. 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, which is converted into the functional compound, is applied to the sulfur particles, to form coated 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.
