COMPOSITION FOR PREPARING POROUS INSULATING LAYER, ELECTRODE FOR NON-AQUEOUS RECHARGEABLE LITHIUM BATTERY, NON-AQUEOUS RECHARGEABLE LITHIUM BATTERY, METHOD OF PREPARING ELECTRODE FOR NON-AQUEOUS RECHARGEABLE LITHIUM BATTERY

A composition for preparing a porous insulating layer for a non-aqueous electrolyte rechargeable battery, the composition including a polyolefin-based polymer particle, a binder, an insulating inorganic particle, and a solvent including water and an organic solvent. The binder includes a polymer, and the polymer includes at least one monomer unit (A) represented by Chemical Formula 1 and at least one monomer unit (B) represented by Chemical Formula 2, where a weight ratio (A)/(B) of the monomer unit (A) and the monomer unit (B) ranges from about 40/60 to about 80/20:
