CATHODE FOR A LITHIUM SECONDARY BATTERY, METHOD OF PREPARING THEREOF, AND LITHIUM SECONDARY BATTERY COPRISING THE SAME |
摘要 |
A cathode for a lithium secondary battery is provided to realize improved voltage characteristics and increased battery capacity, and to impart improved safety and lifespan characteristics to a lithium secondary battery. A cathode for a lithium secondary battery has a multi-layer structure that comprises at least two layers of: a first electrode(55a) comprising a first cathode active material layer(53a) and formed on a first current collector(51a); and a second electrode plate(56a) comprising a second cathode active material layer(54a) and formed on a second current collector(52a), wherein the first cathode active material layer and the second cathode active material layer comprise different lithium metal composite oxides. |
