1. A binder composition for use in an electrode slurry composition, wherein the binder composition comprises:
(i) a polymer comprising a fluoropolymer dispersed in an organic medium comprising at least 90% by weight of an organic solvent, based on the total weight of the organic medium; and
(ii) a dispersant comprising an addition polymer comprising constitutional units comprising the residue of a heterocyclic group-containing ethylenically unsaturated monomer comprising vinyl pyrrolidone.
