Abstract

It is becoming increasingly important to create novel energy storage devices with excellent cycle stability, high power density and high energy density due to the fast advancement in technology. Rechargeable batteries and electrochemical supercapacitors (SCs) are developed as energy storage devices to meet these energy requirements. In this work, a cobalt selenide embedded in a carbon matrix (Co_6.8Se₈@C) produced from ZIF-12 via a one-pot method by our group for the first time was used as an asymmetric SC electrode. In this work, a cobalt selenide embedded in a carbon matrix (Co_6.8Se₈@C) produced from ZIF-12 as a precursor by our group previously has been used as an asymmetric SC electrode. The effects of the structural and morphological properties of this composite material on its electrochemical behaviour and capacitive performance were examined both in a three-electrode system as a single electrode and in an asymmetric SC. The superior electrochemical storage performance with a specific capacitance of 77.06 Fg⁻¹ at 1 Ag⁻¹ and energy density of 27.09 Wh kg⁻¹ at a power density of 441.90 W kg⁻¹ were obtained with high stability and cycle life via the prepared electrode in asymmetric SC device.

期刊介绍： All new compounds should be satisfactorily identified and proof of their structure given according to generally accepted standards. Structural reports, such as papers exclusively dealing with synthesis and characterization, analytical techniques, or X-ray diffraction studies of metal-organic or organometallic compounds will not be considered. The editors reserve the right to refuse without peer review any manuscript that does not comply with the aims and scope of the journal. Applied Organometallic Chemistry publishes Full Papers, Reviews, Mini Reviews and Communications of scientific research in all areas of organometallic and metal-organic chemistry involving main group metals, transition metals, lanthanides and actinides. All contributions should contain an explicit application of novel compounds, for instance in materials science, nano science, catalysis, chemical vapour deposition, metal-mediated organic synthesis, polymers, bio-organometallics, metallo-therapy, metallo-diagnostics and medicine. Reviews of books covering aspects of the fields of focus are also published.
