Abstract

A curable composition in the form of a slurry comprises an electrode particulate material; a (meth)acrylate oligomer; a solvent; an adhesion promoter comprising a (meth)acrylated phosphate ester; and optionally a (meth)acrylate monomer and/or a free radical photoinitiator. This composition is suitable for use in the fabrication of electrodes of lithium ion batteries. In particular, the composition may be applied to a current collector, then cured to form a cathode or an anode. It has been found that this composition provides electrodes having an homogeneous surface which is deprived of cracks and also enhanced adhesion of the electrode particulate material to current collectors used in lithium-ion batteries.
