Abstract
Provided is a lithium secondary battery comprising a lithium transition metal compound-containing cathode and a graphitized carbon-containing anode with addition of a surfactant to the cathode and/or the anode, whereby the addition of the surfactant improves the wettability of an electrolyte on the electrode, thereby increasing the battery capacity and improving rate properties and cycle properties of the battery, in conjunction with a significant reduction of a manufacturing process time of the battery.
