Im working with a cathode material that is soluble in water, NMP, DMF etc., common solvent used for dissolving the popular binders like PVDF, CMC, PTFE etc. My material is not soluble in acetonitrile (ACN) alone. I tried PVAC (polyvinylacetate) but it is soluble in EC:DEC. So could someone suggest me a binder that is soluble in ACN and not in conventional electrolyte solvents.
