Abstract
A lithium secondary battery has an anode, a cathode, a separator between the anode and the cathode and a non-aqueous electrolyte. The non-aqueous electrolyte includes a lithium salt; and a non-linear carbonate-based mixed organic solvent in which (a) a cyclic carbonate compound, and (b) a propionate-based compound are mixed at a volume ratio (a:b) in the range from about 10:90 to about 70:30, and optionally (c) a vinylene carbonate; and an inhibitor against a reaction between the anode and the propionate-based ester compound. The cathode has a current density in the range from about 3.5 to about 5.5 mA/cm2 and a porosity in the range from about 18 to about 35%. This battery may be manufactured as a high-loading lithium secondary battery.
