“…Numerous titanium-based materials are known as electrochemically active as host materials for Li insertion. In contrast, only two materials, NASICON-type NaTi 2 (PO 4 ) 3 82,83 and TiS 2 , 84,85 were reported for the Na counterpart before 2010. Researchers in the field of battery materials have explored titanium-based materials as potential negative electrodes for NIBs, and many related publications have appeared in the past few years.…”

Research interest in Na-ion batteries has increased rapidly because of the environmental friendliness of sodium compared to lithium. Throughout this Perspective paper, we report and review recent scientific advances in the field of negative electrode materials used for Na-ion batteries. This paper sheds light on negative electrode materials for Na-ion batteries: carbonaceous materials, oxides/phosphates (as sodium insertion materials), sodium alloy/compounds and so on. These electrode materials have different reaction mechanisms for electrochemical sodiation/desodiation processes. Moreover, not only sodiation-active materials but also binders, current collectors, electrolytes and electrode/electrolyte interphase and its stabilization are essential for long cycle life Na-ion batteries. This paper also addresses the prospect of Na-ion batteries as low-cost and long-life batteries with relatively high-energy density as their potential competitive edge over the commercialized Li-ion batteries.

“…A different class of solids that shares many similarities with these layered crystals but received considerably less attention are quasi-one-dimensional (quasi-1D) materials. − Titanium trisulfide (TiS 3 ) is a representative quasi-1D material. It is an n-type semiconductor with a band gap of about 1 eV. − It was studied for several decades with regard to its prospects for energy storage applications, − but recently received a surge of attention due to the theoretical predictions of high electron mobilities , and promising thermoelectric properties. ,, The crystal structure of TiS 3 is shown in Figure a . Similar to the layered crystals, quasi-1D materials are built through interplay of strong covalent bonds and weak van der Waals-like interactions.…”

Quasi-1D TiS₃ Nanoribbons: Mechanical Exfoliation and Thickness-Dependent Raman Spectroscopy

et al. 2018

Quasi-one-dimensional (quasi-1D) materials enjoy growing interest due to their unusual physical properties and promise for miniature electronic devices. However, the mechanical exfoliation of quasi-1D materials into thin flakes and nanoribbons received considerably less attention from researchers than the exfoliation of conventional layered crystals. In this study, we investigated the micromechanical exfoliation of representative quasi-1D crystals, TiS3 whiskers, and demonstrate that they typically split into narrow nanoribbons with very smooth, straight edges and clear signatures of 1D TiS3 chains. Theoretical calculations show that the energies required for breaking weak interactions between the two-dimensional (2D) layers and between 1D chains within the layers are comparable and, in turn, are considerably lower than those required for breaking the covalent bonds within the chains. We also emulated macroscopic exfoliation experiments on the nanoscale by applying a local shear force to TiS3 crystals in different crystallographic directions using a tip of an atomic force microscopy (AFM) probe. In the AFM experiments, it was possible to slide the 2D TiS3 layers relative to each other as well as to remove selected 1D chains from the layers. We systematically studied the exfoliated TiS3 crystals by Raman spectroscopy and identified the Raman peaks whose spectral positions were most dependent on the crystals’ thickness. These results could be used to distinguish between TiS3 crystals with thickness ranging from one to about seven monolayers. The conclusions established in this study for the exfoliated TiS3 crystals can be extended to a variety of transition metal trichalcogenide materials as well as other quasi-1D crystals. The possibility of exfoliation of TiS3 into narrow (few-nm wide) crystals with smooth edges could be important for the future realization of miniature device channels with reduced edge scattering of charge carriers.

“…Sodium-ion batteries (SIBs) have been considered as a promising alternative to lithium-ion batteries (LIBs) due to the natural abundance and low cost of sodium sources. − Unfortunately, because of the larger radius (1.02 Å) of the sodium ion compared to that of the lithium ion (0.76 Å), many intercalated/deintercalated anode materials suitable for LIB systems show sluggish sodium-ion diffusion kinetics and poor electrochemical performance, which cannot be directly applied in SIB systems. , For example, graphite, which is a successful commercial anode material of LIBs, however, cannot intercalate sodium ions effectively because of the limited interlayer space. , Although some other anode materials have been explored and proven to be effective in realizing sodium intercalation/deintercalation, limited by the intrinsic intercalation chemistry whose reactions contain few electrons, their capacity is relatively low and hard to enhance. − Moreover, the layer structures of these materials are severely distorted during sodium intercalation/deintercalation, which will cause the destruction and collapse of the material structure, leading to poor cycle stability and rate capability. , Therefore, exploitation of the suitable anode material that can enable high capacity and favorable sodium storage is crucial for the development of SIBs.…”

Different from the ion intercalation/deintercalation, conversion-based reactions are a promising way to achieve high capacity of storage materials. However, their too much volume change and poor reversibility during discharge/charge are stubborn to overcome. Herein, by combining hydrothermal synthesis and chemical vapor deposition, a Co9S8 nanorod encapsulated by a N-doped carbon shell (r-Co9S8@NC) is built and applied as an anode material for sodium-ion batteries. Benefiting from the advantages of the chamber-confined conversion and sodiophilic interface offered by the N-doped carbon shell, the Co9S8 redox was well restrained in the shell with improved kinetics, which can not only alleviate the Co9S8/electrolyte side reaction and suppress the large volume expansion and aggregation of Co9S8 nanorods but also enhance the sodium storage/diffusion ability. As expected, the r-Co9S8@NC electrodes exhibit a high capacity of 675 mAh g–1 at 50 mA g–1, an excellent rate capability (342 mAh g–1 at 10 A g–1), and a good cycling stability (317 mAh g–1 after 1500 cycles at 5 A g–1 and 483 mAh g–1 after 150 cycles at 500 mA g–1) among which the rate capability is outperforming most of the reported metal-sulfide-based anodes. Further, the sodium storage mechanism and the good reversibility of the r-Co9S8@NC electrode have been revealed and confirmed by the XRD and XPS characterizations. This work provides an effective strategy to design storage materials based on a chamber-confined conversion reaction.

The Behavior of Na ‐ TiS2 and Na ‐ TiS3 as Solid Solution Electrodes

Abstract: We have investigated the behavior of TiS2 and TiS3 electrodes in a sodium cell at temperatures between 230° and 280°C using the solid electrolyte β″‐alumina. The electrochemical reaction of TiS2 with sodium was found to be reversible, while TiS3 was found to decompose.
