Special Issue Information

Dear Colleagues,

Low-dimensional (zero-dimensional [0D], one-dimensional [1D], and two-dimensional [2D]) nanomaterials have been particularly interested in electrochemical and optoelectronic applications due to their unique structure and physical/chemical properties. The capability of applying the unique properties to electrochemical and optoelectronic application will have a significant impact on the nanotechnology, industry and society. This special issue is intended to gather cutting-edge research in the field. We will summarize and highlight the current status of the field of low dimensional nanostructures for electrochemical and optoelectronic. 

We would like to invite you to submit a manuscript to this Special Issue “Low Dimensional Nanostructures for Electrochemical and Optoelectronic”. Both experimental and theoretical contributions are welcome. Research topics of interest may include, but are not limited to: 

  • 1D nanomaterials (TiO2, Fe2O3, ZnO, Si, Ge, etc.)
  • 2D nanomaterials (Graphene, Carbon nitride, Transition metal dichalcogenides, etc.)
  • MOFs and COFs
  • Quantum dots
  • PEC water splitting
  • Photoluminescence spectrum
  • Batteries
  • Supercapacitors

Silicon, as a promising next-generation anode material, has drawn special attention from industries due to its high theoretical capacity (around 3600 mAh g−1) in comparison with conventional electrodes, e.g., graphite. However, the fast capacity fading resulted by a large volume change hinders the pragmatic use of Si anodes for lithium ion batteries. In this work, we propose an efficient strategy to improve the cyclability of upcycled Si nanomaterials through a simple battery operation protocol. When the utilization degree of Si electrodes was decreased, the electrode deformation was significantly alleviated. This directly led to an excellent electrochemical performance over 100 cycles. In addition, the average charge (delithation) voltage was shifted to a lower voltage, when the utilization degree of electrodes was controlled. These results demonstrated that our strategic approach would be an effective way to enhance the electrochemical performance of Si anodes and improve the cost-effectiveness of scaling-up the decent nanostructured Si material.

Metallic Li has caught the attention of researchers studying future anodes for next-generation batteries, owing to its attractive properties: high theoretical capacity, highly negative standard potential, and very low density. However, inevitable issues, such as inhomogeneous Li deposition/dissolution and poor Coulombic efficiency, hinder the pragmatic use of Li anodes for commercial rechargeable batteries. As one of viable strategies, the surface functionalization of polymer separators has recently drawn significant attention from industries and academics to tackle the inherent issues of metallic Li anodes. In this article, separator-coating materials are classified into five or six categories to give a general guideline for fabricating functional separators compatible with post-lithium-ion batteries. The overall research trends and outlook for surface-functionalized separators are reviewed. Full article
