| 摘要 |
The present invention relates to a carbon nanotube/manganese dioxide yarn electrode comprising: a yarn type carbon nanotube yarn which is prepared by twisting a carbon nanotube sheet and has a plurality of pores therein; and manganese dioxide deposited on a surface or in inner pores of the carbon nanotube yarn, and to a yarn type super capacitor comprising the same. The super capacitor has excellent mechanical strength and flexibility while having high specific capacity, energy density, and power density, and thus can retain superior electrochemical performances even under several modifications, such as twisting, bending, and weaving. |
