Special Issue Information

Dear Colleagues,

As concerns regarding the sustainability and cost of lithium-ion batteries (LIBs) continue to grow, it is important to shift our research and development focus towards cheaper and safer alternatives for energy storage applications. Sodium-ion batteries (SIBs) have raised tremendous interest due to sodium’s low cost and high abundance in the Earth’s crust. However, compared with the current LIBs technology, SIBs often have compromised electrochemical performance such as lower capacities and poor cycling performance, which are due to the following issues, as well as others:

  • Local structural changes of the cathodes.
  • Surface degradation of the cathodes.
  • Formation of unstable solid-electrolyte interphase on the anodes.

It is difficult to provide engineering solutions to improve the cell performance before we can better understand the SIBs system with various types of cathodes and anodes. Fundamental characterizations such as phase and morphology characterizations using X-ray diffraction (XRD) and scanning electron microscopy (SEM), and electrochemical characterizations such as galvanostatic charge/discharge, cycling, and rate performance tests are inadequate to deep dive into the change with materials’ local environment. Therefore, advanced characterizations on SIBs electrodes or cells are crucial to diagnose the failure mechanism of each system. This Special Issue invites the submission of original research on advanced characterizations for SIBs including, but not limited to, the following techniques:

  • In-situ measurements such as in-situ transmission electron microscopy (TEM), in-situ atomic force microscopy (AFM).
  • Neutron diffraction and pair distribution function (PDF) analysis.
  • 3D tomography.
  • X-ray absorption near edge structure (XANES) with extended X-ray absorption fine structure (EXAFS).
  • Solid-state nuclear magnetic resonance (NMR) spectroscopy.

Sodium-ion batteries (SIBs) have emerged as promising alternatives to their lithium-ion counterparts due to the abundance of sodium resources and their potential for cost-effective energy storage solutions. The chemistry for SIBs has been investigated since the 1980s, but it went through a slow research and development process. Recently, there has been an acceleration in technology maturation due to a supply chain crisis originating from unequal resource distribution and sustainability and safety concerns regarding lithium-ion batteries. However, the practical application of SIBs has been hindered primarily by challenges related to cathode materials, specifically, surface and structural stabilities in different conditions. Through the integration of advanced techniques such as in situ spectroscopy, operando diffraction, and high-resolution microscopy, a comprehensive understanding of the cathode’s dynamic behavior and degradation mechanisms can be achieved. The identified structural modifications, phase transitions, and degradation pathways offer critical insights into the design of robust cathode materials with prolonged cycling stability, fast charging capability, high energy density, great low-temperature performance, and safety. This review underscores the pivotal role of cutting-edge characterization techniques in guiding the development of high-performance sodium-ion batteries, thereby fostering the realization of sustainable and efficient energy storage solutions for diverse technological applications.
