Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 1. A cathode of a three-dimensional lithium secondary battery, wherein the cathode is defined by a sintered body comprising a cathode active material, 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, wherein the cathode is disposed on a cathode collector of the three-dimensional lithium secondary battery to be perpendicular to the cathode collector. 2. The cathode of the three-dimensional lithium secondary battery of claim 1 , wherein the cathode active material comprises a plurality of elliptical or circular grains which is irregularly stacked when viewed in a side cross-sectional view of the cathode. 3. The cathode of a three-dimensional lithium secondary battery of claim 1 , wherein the electrode density of the sintered body is in a range of about 4.0 g/cc to about 4.6 g/cc. 4. The cathode of the three-dimensional lithium secondary battery of claim 1 , wherein the cathode active material comprises a lithium transition metal oxide. 5. The cathode of the three-dimensional lithium secondary battery of claim 4 , wherein the cathode active material comprises a lithium cobalt oxide. 6. The cathode of the three-dimensional lithium secondary battery of claim 1 , wherein the cathode comprises an inner collector and cathode layers, which are respectively disposed on opposite sides of the inner collector.
