Positive Electrode for Lithium-Sulfur Secondary Battery and Method of Forming the Same |
摘要 |
Provided are a positive electrode for a lithium-sulfur secondary battery and a method of forming the same, the positive electrode being capable of maintaining battery characteristics such as a specific capacity and a cycling characteristic while achieving a high rate characteristic in particular when being applied to a lithium-sulfur secondary battery. A positive electrode of a lithium-sulfur secondary battery includes a positive electrode current collector and carbon nanotubes grown on a surface of the positive electrode current collector and oriented in a direction orthogonal to the surface. At least the surface of each of the carbon nanotubes is covered with sulfur with a certain interstice left between neighboring ones of the carbon nanotubes.
