Special Issue "Sodium-Ion Battery: Materials and Devices"
A special issue of Batteries (ISSN 2313-0105).
Deadline for manuscript submissions: 31 May 2018
Room-temperature sodium-ion batteries (NIBs) may offer key benefits over other commercial battery technologies such as lithium-ion batteries and lead-acid batteries in cost, safety, and performance. Due to the highly abundant sodium source (seawater), the materials are not geographically limited in terms of supply, and thanks to improved safety implications for transport due to novel cell designs, NIBs offer potential alternative energy storage solutions to lithium-ion batteries for applications where cost and safety are key drivers.
NIB technology is still in its infancy, and despite recent advances, significant knowledge gaps still exist. Sodium-ion cell chemistries require research into materials, electrochemical testing methods, materials processing for electrodes, novel electrolyte systems, and a greater knowledge of the failure mechanisms for safety and performance. This special issue “Sodium-Ion Battery: Materials and Devices” will focus on aspects of advancements in sodium-ion technology.
Potential topics include but are not limited to:
- - Novel sodium-ion materials, positive, negative, and electrolytes;
- - Electrode design;
- - Electrochemical test method;
- - NIB cell design;
- - Safety failure analysis;
- - Performance lifetime and degradation studies.

Abstract: p-block elements have been recently shown to be viable alternatives to hard carbon as negative electrode materials for Na-ion batteries, showing interesting performance with reversible capacities exceeding 400 mAh/g. Among them, Sb seems to have a specific affinity for Na, showing excellent cycling stability even in the simplest form of bulk Sb powder despite a huge volume expansion during the alloying process. The reason of this affinity has not been totally understood yet: while the electrochemical signature suggests the formation of several possible intermediates, the Na-Sb phase diagram indicates the existence of only one phase between the end member species formed during cycling, Sb and Na3Sb. Moreover, such intermediates are amorphous and thus totally indistinguishable by X-ray diffraction (XRD). Recently, we have studied the mechanism by Pair Distribution Function (PDF) analysis of synchrotron XRD data, and proposed possible short-range structures and compositions for the intermediates formed with pure Sb. With the goal of better understanding this specific affinity of Na for Sb, the electrochemical reaction of Sb with Na was thoroughly studied by operando X-ray absorption spectroscopy (XAS). Sb K-edge XAS data were analysed using adapted chemometric tools (Principal Component Analysis and Multivariate Curve Resolution) in order to extract all information on the mechanisms of three compounds. The results of this analysis show that, while it is possible to gather important information for the reconstruction of the reaction paths, it is intrinsically impossible to prove by XAS the formation of some of the intermediates proposed in the case of Sb electrodes.
