| titleOfInvention |
Separator, method of preparing the same, and lithium battery including the same |
| abstract |
A separator includes a substrate and a coating layer on at least one surface of the substrate, wherein the coating layer includes first organic particles and second organic particles, and an average particle diameter of the first organic particles is larger than an average particle diameter of the second organic particles. The first organic particles protrude or extend to a height of about 0.1 μm to about 0.5 μm from a dented portion of a surface of the coating layer, and are distributed on the surface of the coating layer in an area ratio of about 5% or greater to less than 30% with respect to a total surface area of the coating layer. The separator may have improved adhesion to electrodes, insulation characteristics, and air permeability, and a battery including the separator may have improved lifespan characteristics. |
