Bacterial-Cellulose-Derived Carbon Nanofiber@MnO2 and Nitrogen-Doped Carbon Nanofiber Electrode Materials: An Asymmetric Supercapacitor with High Energy and Power Density
A new kind of high‐performance asymmetric supercapacitor is designed with pyrolyzed bacterial cellulose (p‐BC)‐coated MnO2 as a positive electrode material and nitrogen‐doped p‐BC as a negative electrode material via an easy, efficient, large‐scale, and green fabrication approach. The optimal asymme...

Zusammenfassung: | A new kind of high‐performance asymmetric supercapacitor is designed with pyrolyzed bacterial cellulose (p‐BC)‐coated MnO2 as a positive electrode material and nitrogen‐doped p‐BC as a negative electrode material via an easy, efficient, large‐scale, and green fabrication approach. The optimal asymmetric device possesses an excellent supercapacitive behavior with quite high energy and power density. |
