Abstract
A cathode of a three-dimensional lithium secondary is defined by a sintered body including a cathode active material, in which a thickness of the sintered body is in a range of about 5 μm to about 30 μm, and an electrode density of the sintered body is in a range of about 3.7 g/cc to about 4.6 g/cc. The cathode active material may include a lithium cobalt oxide.
