Abstract
The present disclosure relates to a lithium secondary battery which ensures reaction uniformity even though it uses a high-loading electrode, and thus has high capacity and improved cycle characteristics. The lithium secondary battery includes: an electrode assembly including a positive electrode, a negative electrode and a separator interposed between the positive electrode and the negative electrode; an electrolyte including a lithium salt and an organic solvent; and a battery casing receiving the electrode assembly and the electrolyte, wherein the positive electrode has a loading amount of 3.5 mAh/cmor more, the separator has an air permeability of 200-1200 sec/100 mL, and the electrolyte has a lithium ion conductivity of 11-20 mS/cm.
