Disclosed is a binder for a lithium-sulfur battery including a
butadiene-based copolymer. The binder exhibits chemical resistance to
polysulfides, is stable a battery working temperatures, forms an emulsion
in organic solvents and exhibits high adherence to positive active
materials and electrodes used in the lithium-sulfur battery. The
disclosed binder compositions, due to their high adherence to positive
active materials allow for higher relative amounts of positive active
materials to be used in the battery resulting in a high capacity
lithium-sulfur battery.
