Special Issue Information

Dear Colleagues,

With the ever-growing electronic products and electric vehicles, higher requirements have been put forward for energy storage devices such as rechargeable batteries and electrochemical capacitors, etc. Developing high-performance energy storage materials is currently a research hotspot, which helps promote technological progress and sustainable social development. Accordingly, we are launching this new Special Issue of Nanomaterials titled “Enhancing Energy Storage in Batteries and Devices Through Nanoscale Strategies”, which will focus on the fundamental and application areas of advanced materials for batteries and other energy storage devices.

In this Special Issue, original research articles and reviews are welcome. Research areas may include (but are not limited to) the following:

  • Batteries (such as lithium-/sodium-/potassium-ion batteries, aqueous zinc-ion batteries, Li-S batteries, solid-state batteries, etc.);
  • Capacitors;
  • Synthesis, analysis, or mechanism research of advanced energy storage materials;
  • Theoretical calculation of advanced energy storage materials;
  • Other types of energy storage applications.

We look forward to receiving your contributions.

Developing free-standing electrodes without the need of metal current collectors, binders, and conductive additives are essential for promoting the development of sodium-ion batteries (SIBs) to attain higher energy density. In this study, we developed and effectively synthesized a novel three-dimensional free-standing sodium-ion battery anode material with the composition of Bi@MoS2@C carbon nanofibers by cleverly utilizing the energy storage advantages of each material. By growing MoS2 nanospheres on Bi carbon nanofibers and coating them with a carbon layer, this free-standing system achieves both structural optimization and synergistic performance enhancement. Experimental results show that this composite electrode has a remarkably high initial specific capacity of 275.31 mA h g−1 at a current density of 0.5 A g−1, significantly exceeding that of Bi carbon nanofibers (150.6 mA h g−1). Furthermore, it retains a capacity retention of 96.07% after 800 cycles, which significantly exceeds that of pristine MoS2 (72.33 mA h g−1) as a sodium-ion battery anode. The significant performance improvement originates from the free-standing structural design and synergistic effects of Bi carbon nanofibers, MoS2 nanospheres and carbon layer, which not only provide 3D electron transport pathways and improved conductivity but also effectively accommodate volume changes during the charging and discharging processes. This work offers a promising and practical strategy for designing high-performance free-standing energy storage electrodes through hybrid mechanisms and synergistic effects. Full article
