A novel B/N co-doped carbon nanospheres framework is synthesized by a facile, economic, environmental and scalable method. The as-obtained materials display extra-high capacitive performance and exceptional long cycle stability with the merits of high energy and power density. We believe that this material will be applicable in the application of integrated energy storage devices.

The development of manganese dioxide (MnO[Formula: see text] as the cathode for aqueous Zn-MnO2 batteries is hindered by poor capacity. Herein, we propose a high-capacity MnO2 cathode constructed by engineering it with N-doping (N-MnO[Formula: see text] for a high-performance Zn-MnO2 battery. Benefiting from N element doping, the conductivity of N-MnO2 nanorods (NRs) electrode has been improved and the dissolution of the cathode during cycling can be relieved to some extent. The fabricated Zn-N-MnO2 battery based on the N-MnO2 cathode and a Zn foil anode presents an a real capacity of 0.31[Formula: see text]mAh[Formula: see text]cm[Formula: see text] at 2[Formula: see text]mA[Formula: see text]cm[Formula: see text], together with a remarkable energy density of 154.3[Formula: see text]Wh[Formula: see text]kg[Formula: see text] and a peak power density of 6914.7[Formula: see text]W[Formula: see text]kg[Formula: see text], substantially higher than most recently reported energy storage devices. The strategy of N doping can also bring intensive interest for other electrode materials for energy storage systems.
