Compositions for forming a porous insulating layer, electrode for non-aqueous electrolyte rechargeable battery, rechargeable battery including the electrode and method of manufacturing the electrode

A method for manufacturing an electrode for a non-aqueous electrolyte rechargeable battery, the method comprising:

• forming a porous insulating layer on an active material layer on a current collector, the porous insulating layer being formed utilizing a composition to form a porous insulating layer,
• wherein the active material layer comprises an active material to electrochemically intercalate and deintercalate lithium ions and an active material layer binder,
• the composition to form the porous insulating layer comprises a solvent comprising an organic solvent, an insulating inorganic particle, and a porous insulating layer binder, and
• the porous insulating layer binder is a polymer obtained by polymerization of monomers selected from the group consisting of about 30 wt % to about 60 wt % of an aromatic vinyl compound, about 20 wt % to about 69 wt % of (meth)acrylic acid ester, about 5 wt % to about 35 wt % of (meth)acrylic acid ester comprising a hydroxy group or an ether group, and about 1 wt % to about 10 wt % of a vinyl compound comprising an acidic functional group, based on a total weight of the binder,
• wherein a distance between Hansen solubility parameters of the active material layer binder and the organic solvent is greater than or equal to about 8.0 MPa1/2.
