Special Issue Information

Dear Colleagues,

Currently, the most desired electrochemical energy storage/conversion devices for social development are rechargeable batteries and supercapacitors that combine high energy efficiency, low cost, long cycle life, and high safety. Recent research has found that nanoelectrode materials provide significantly improved ion transport and electronic conductivity compared to traditional battery and supercapacitor electrode materials. They also occupy all available embedding sites in the particle volume, achieving high specific capacity, and fast ion diffusion. These characteristics enable nanoelectrode materials to withstand high currents, providing a promising solution for high-energy-density and high-power-density energy storage/conversion devices. On the other hand, energy storage/conversion devices have been developed vigorously, such as alkali metal-ion batteries, alkali metal batteries, alkali metal sulfur batteries, and supercapacitors. By combining 2D nanostructured materials with high electronic conductivity and high energy density, or assembling them into 3D electrodes at the nanoscale, the electrochemical performance of the devices is significantly improved.

This Special Issue will comprehensively introduce the progress of nanostructures in improving performance of batteries and supercapacitors. This includes the use of spraying, 3D printing, rolling, electrodeposition, layer-by-layer deposition, vacuum filtration, etc. Only by developing convenient and low-cost processing methods for assembling nanoelectrode materials into devices, we take advantage of the advantages of nanoelectrode materials in energy storage/conversion field, which contribute to the development of the energy storage/conversion field. We invite authors to publish original research and review articles covering the current progress of batteries and supercapacitors with nanoelectrodes. Potential themes include, but are not limited to:

  1. Alkali metal-ion batteries based on nanostructured electrodes;
  2. Alkali metal batteries based on nanostructured electrodes;
  3. Alkali metal sulfur/selenium batteries based on nanostructured electrodes;
  4. Air batteries based on nanostructured electrodes;
  5. Supercapacitors based on nanostructured electrodes.

The application of transition metal hydroxides has long been plagued by its poor conductivity and stability as well as severe aggregation tendency. In this paper, a novel hierarchical core–shell architecture, using an F-doped Co(OH)2 nanorod array (Co(OH)F) as the core and Mn/Ni co-doped Co(OH)2 nanosheets (NiCoMn-LDH) as the shell, was constructed via an MOF-mediated in situ generation method. The obtained Co(OH)F@ NiCoMn-LDH composites exhibited excellent supercapacitive performance with large specific capacitance as well as improved rate capability and long-term stability. The effect of the Ni/Mn ratio on the supercapacitive performance and energy storage kinetics was systematically investigated and the related mechanism was revealed. Full article

Lithium–sulfur batteries (LSBs) have become the most promising choice in the new generation of energy storage/conversion equipment due to their high theoretical capacity of 1675 mAh g−1 and theoretical energy density of 2600 Wh kg−1. Nevertheless, the continuous shuttling of lithium polysulfides (LiPSs) restricts the commercial application of LSBs. The appearance of layered double hydroxides (LDH) plays a certain role in the anchoring of LiPSs, but its unsatisfactory electronic conductivity and poor active sites hinder its realization as a sulfur host for high-performance LSBs. In this paper, metal organic framework-derived and Ce ion-doped LDH (Ce-Ni/Fe LDH) with a hollow capsule configuration is designed rationally. The hollow structure of Ce-Ni/Fe LDH contains a sufficient amount of sulfur. Fe, Ni, and Ce metal ions effectively trap LiPSs; speed up the conversion of LiPSs; and firmly anchor LiPSs, thus effectively inhibiting the shuttle of LiPSs. The electrochemical testing results demonstrate that a lithium–sulfur battery with capsule-type S@Ce-Ni/Fe LDH delivers the initial discharge capacities of 1207 mAh g−1 at 0.1 C and 1056 mAh g−1 at 0.2 C, respectively. Even at 1 C, a lithium–sulfur battery with S@Ce-Ni/Fe LDH can also cycle 1000 times. This work provides new ideas to enhance the electrochemical properties of LSBs by constructing a hollow capsule configuration. Full article
