Special Issue Information

Dear Colleagues,

In this Special Issue, I would like to invite submissions of papers on advanced electrode materials and novel device designs for the latest supercapacitors. With the increasing importance of electrochemical energy storage, the development of supercapacitors is accelerating. Many advanced materials have been used as supercapacitor electrodes like carbon-based nanomaterials, metal oxides/sulfides/selenides/phosphides, conducting polymers and hybrid nanocomposites along with some novel materials like MXenes, metal-organic frameworks, metal nitrides, and covalent organic frameworks. Various novel supercapacitor device designs such as flexible supercapacitors, micro-supercapacitors, battery-supercapacitor hybrid devices, electrochromic supercapacitors, photo-supercapacitors, thermally chargeable supercapacitors, high-frequency supercapacitors and self-healing supercapacitors have also been developed for high performance or special applications. It is expected that these advanced electrode materials and emerging device designs will propel supercapacitors to get a limitless foreground in the future.

This Special Issue covers various topics related to advanced electrode materials and novel device designs for the latest supercapacitors, including but not limited to the following topics:

  • Metal oxides/sulfides/selenides/phosphides;
  • Metal-organic frameworks;
  • Covalent organic frameworks;
  • Two-dimensional ultrathin materials;
  • Carbon-based nanomaterials;
  • Conducting polymers;
  • Flexible supercapacitors;
  • Micro-supercapacitors;
  • Battery-supercapacitor hybrid devices;
  • High-frequency supercapacitors;
  • Electrochromic supercapacitors;
  • Self-healing supercapacitors.

This study reports the facile synthesis of rationally designed composite materials consisting of nitrogen-doped graphene quantum dots (N-GQDs) and MnCO3/ZnMn2O4 (N/MC/ZM) on Ni foam using a simple hydrothermal method to produce high-performance supercapacitor applications. The N/MC/ZM composite was uniformly synthesized on a Ni foam surface with the hierarchical structure of microparticles and nanosheets, and the uniform deposition of N-GQDs on a MC/ZM surface was observed. The incorporation of N-GQDs with MC/ZM provides good conductivity, charge transfer, and electrolyte diffusion for a better electrochemical performance. The N/MC/ZM composite electrode delivered a high specific capacitance of 960.6 F·g−1 at 1 A·g−1, low internal resistance, and remarkable cycling stability over 10,000 charge–discharge cycles. Additionally, an all-flexible solid-state asymmetric supercapacitor (ASC) device was fabricated using the N/MC/ZM composite electrode. The fabricated ASC device produced a maximum energy density of 58.4 Wh·kg−1 at a power density of 800 W·kg−1 and showed a stable capacitive performance while being bent, with good mechanical stability. These results provide a promising and effective strategy for developing supercapacitor electrodes with a high areal capacitance and high energy density. Full article
