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.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Energies is an international peer-reviewed open access semimonthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
