Recently, a research team led by Prof. Zhao Bangchuan from the Institute of Solid Materials of the Hefei Institutes of Physical Science (HFIPS) synthesized 3D porous honeycomb-like CoN-Ni3N/N-C nanosheets and vanadium nitride (VN) nanobelt arrays via in-situ growth method, respectively, and constructed a high-energy-density flexible supercapacitor device. The result has been published in Advanced Functional Materials.Recently, a research team led by Prof. Zhao Bangchuan from the Institute of Solid Materials of the Hefei Institutes of Physical Science (HFIPS) synthesized 3D porous honeycomb-like CoN-Ni3N/N-C nanosheets and vanadium nitride (VN) nanobelt arrays via in-situ growth method, respectively, and constructed a high-energy-density flexible supercapacitor device.
