Abstract
The present invention relates to a lithium secondary battery, and more specifically to a lithium secondary battery having a multi-directional lead-tab structure. The lithium secondary battery of the present invention includes: an electrode assembly which is formed by alternately laminating an electrode plate having a current collector, an active material, and a tab, and an isolation layer; a lead which is electrically connected to the tab; and a battery case, wherein the lead is divided into an anode lead and a cathode lead, and at least two or more anode leads and cathode leads are provided. The battery of the present invention uses the same lead-tab size as the prior art and is suitable for use with high current.
