Abstract

Disclosed are a composition for forming a porous insulating layer for suppressing a layer thickness increase of an active material layer of an electrode, a method for manufacturing an electrode for a non-aqueous electrolyte rechargeable battery, and an electrode for a non-aqueous electrolyte rechargeable battery manufactured according to the method and a non-aqueous electrolyte rechargeable battery.Provided is a composition for forming a porous insulating layer on an active material layer disposed on a main surface of a current collector current collector, wherein the active material layer includes an active material capable of electrochemically intercalating and deintercalating lithium ions and an active material layer binder, the composition for forming the porous insulating layer includes a solvent including an organic solvent, an insulating inorganic particle, and a binder, and the binder is a polymer obtained by polymerization of monomers including 30 wt% to 60 wt% of an aromatic vinyl compound, 20 wt% to 69 wt% of (meth)acrylic acid ester, 5 wt% to 35 wt% of (meth)acrylic acid ester including a hydroxy group or an ether group, and 1 wt% to 10 wt% of a vinyl compound including an acidic functional group based on a total weight of the binder.
