Special Issue Information

Dear Colleagues,

The global community will soon be witnessing a significant scarcity of energy as conventional energy resources are being depleted day by day. Therefore, alternative renewable energy resources such as solar energy, wind energy, ocean energy, etc. are attracting an enormous amount of attention. Unfortunately, almost all renewable energy resources are intermittent in nature, and it is difficult to generate energy continuously. As such, there is a need to store the energy that is produced during the presence of energy sources and utilize it in the absence of energy sources. Supercapacitors are emerging as prominent energy storage devices owing to their unique properties, such as sharp charge/discharge rates and longer lifetimes. However, for commercial usage, the energy density of supercapacitors should be enhanced. Therefore, the current Special Issue focuses on the development of novel electrodes and electrolytes for the enhancement of the energy density of the device. Potential topics of the issue include but are not limited to the following: 

  1. Development of supercapacitors with enhanced storage properties;
  2. Fabrication of supercapacitors using novel electrode materials;
  3. Preparation of solid-state electrolytes;
  4. Fabrication of flexible energy storage devices;
  5. Solid-state supercapacitors;
  6. Cost-effective methods and materials;
  7. New methods to evaluate energy storage devices;
  8. Zinc-ion, magnesium-ion, and sodium-ion based supercapacitors;
  9. Ionic liquid electrolyte-based supercapacitors.

Owing to the unique virtues of specific energy/power densities, lithium-ion capacitors (LICs) have been increasingly attracting research attention. However, the LICs are greatly restrained by the slow Li+-reaction kinetics of battery-type anodes, which is still a challenging task. In this work, we construct a superior LIC using ultrafine MnO/dual N-doped carbon (MnO/DNC) anode and activated N-doped porous carbon (ANC) derived from a homologous polypyrrole precursor. The uniform MnO ultrafine particles (~10 nm size) are well encapsulated into a dual-carbon framework, which provides fast ion/electron transportation and structural cushion for high-rate and long-durable energy storage. Accordingly, the anodic MnO/DNC achieves an impressive rate performance (179 mAh g−1 @10 A g−1) and a stable 500-cycling lifespan. The as-constructed LICs could deliver a large specific energy of 172 Wh kg−1 at 200 W kg−1 and retain at 37 Wh kg−1 even at a high specific power of 15 kW kg−1. It is believed that the design strategy of confining ultrafine conversion-type anode materials into a dual-carbon structure will expedite the development of advanced LICs. Full article
