The present invention relates to a multi-layered separator for a lithium secondary battery and a lithium secondary battery including the separator. More particularly, the present invention relates to a multi-layered separator prepared by laminating and bonding two or more separator sheets oriented with lithium ion channels, As a result, it was found that water or non-aqueous electrolytes used in both electrodes were not mixed with each other, resulting in increased battery performance and lifetime. |
