Ni-Doped Cobalt–Cobalt Nitride Heterostructure Arrays for High-Power Supercapacitors
Abstract
Metal nitrides are widely recognized as a class of desirable supercapacitor electrode materials owing to their high electrical conductivity and structural stability. Embedding metal nanoparticles in nitrides can further enhance the conductivity for electron transport. Herein, a heterostructure consisting of Ni-doped Co–Co 2 N is synthesized by simple thermal annealing of metal–organic framework (MOF)-derived NiCo 2 O 4 in ammonia atmosphere, in the process of which the MOF-derived two-dimensional (2D) nanoflake arrays were well retained, and the metal–metal nitride heterostructure was well established when annealed at 350 °C. Benefiting from the MOF-derived 2D nanoflake morphology and the metal-metal nitride heterostructure, the Ni-doped Co–Co 2 N delivers a specific capacity of 361.93 C/g. A full cell test has been conducted using Ni-doped Co–Co 2 N as the positive electrode and porous carbon as the negative electrode, and it shows an energy density of 20.4 Wh/kg at the power density of 9.85 kW/kg with 82.4% of initial energy density being retained after 5000 cycles.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
