“…According to XRD patterns, the milling time of 1 hour was found to be sufficient to obtain crystalline SnS phase and this phase can be still obtained when the milling time goes up to 20 hours. The 2θ angles and related main peaks are attributed to orthorhombic SnS phase 20,21 . The crystallite size was calculated by using Debye‐Scherrer Equation ().…”

Orthorombic tin (II) sulfide are synthesized by a simple and cost effective mechanochemical method in a high energy ball mill over different time scales. After the detailed characterization by X-ray photoelectron spectroscopy (XPS), X-ray diffraction, Fourier Transform Infrared (FTIR) spectroscopy, thermogravimetricanalysis (TGA), scanning electron microscopy (SEM) and EDX mapping, 2 hours milling time is found to be the optimum as anode in sodium-ion batteries. Later, electrochemical performances are investigated with regards to the binder type; sodium carboxy methyl cellulose (CMC), sodium alginic acid (Na-alginate) and polyvinylidene fluoride (PVdF), in which the best performances are obtained with Na-alginate. Comprehensive electrochemical impedance spectroscopy (EIS) measurements are pursued in order to examine the effect of binders. EIS tests of SnS anodes after Crate test reveal much bigger resistivity with PVdF binder than that of CMC and Na-alginate. Postmortem surface morphology analysis by means of SEMdemonstrates the self-healing properties of Na-alginate binder with no visible crack formation after cycles. As a whole, more than 300 mAh/g capacity is obtained over 60 cycle at C/5 current density without the help of carbon addition during the synthesis of the SnS composite.

“…[ 281 ] Moreover, while the structure can adjust the volume change, its large specific surface area and electrochemical interface region can efficiently promote Na + insertion/extraction. Jia et al [ 268 ] fabricated highly porous SnS hollow nanofibers (SnS HNFs), which provided sufficient interior void space to buffer the volume expansion. The SnS HNF anode delivered an average capacity of 615 mA h g −1 at 0.1 A g −1 after 50 cycles (Figure 12d) and exhibited a high reversible capacity of 645 mA h g −1 at 0.1 A g −1 after 100 cycles.…”

SnSx (x = 1, 2) compounds are composed of earth‐abundant elements and are nontoxic and low‐cost materials that have received increasing attention as energy materials over the past decades, owing to their huge potential in batteries. Generally, SnSx materials have excellent chemical stability and high theoretical capacity and reversibility due to their unique 2D‐layered structure and semiconductor properties. As a promising matrix material for storing different alkali metal ions through alloying/dealloying reactions, SnSx compounds have broad electrochemical prospects in batteries. Herein, the structural properties of SnSx materials and their advantages as electrode materials are discussed. Furthermore, detailed accounts of various synthesis methods and applications of SnSx materials in lithium‐ion batteries, sodium‐ion batteries, and other new rechargeable batteries are emphasized. Ultimately, the challenges and opportunities for future research on SnSx compounds are discussed based on the available academic knowledge, including recent scientific advances.

“…1,31 It has been shown that the hightemperature phase transition from the Pnma to phases alters the sample density and leads to enhanced phonon scattering, further lowering the thermal conductivity. [32][33][34] The indirect band gap also decreases through the phase transition, from 1.09 eV to 0.42 eV in SnS and from 0.61 to 0.39 eV in SnSe. 33,34 Finally, a recent study on SnSe revealed that the rocksalt phase has an even lower lattice thermal conductivity than the orthorhombic phase, suggesting rocksalt SnSe is also a potential high-performance thermoelectric.…”

The tin monochalcogenides SnS and SnSe adopt four different crystal structures, viz. orthorhombic Pnma and Cmcm and cubic rocksalt and π-cubic (P213) phases, each of which has optimal properties for a range of potential applications. This rich phase space makes it challenging to identify the conditions under which the different phases are obtained. We have performed first-principles quasi-harmonic lattice-dynamics calculations to assess the relative stabilities of the four phases of SnS and SnSe. We investigate dynamical stability through the presence or absence of imaginary modes in the phonon dispersion curves, and we compute Helmholtz and Gibbs free energies to evaluate the thermodynamic stability. We also consider applied pressures from 0-15 GPa to obtain temperature-pressure phase diagrams. Finally, the relationships between the different crystal phases are investigated by explicitly mapping the potential-energy surfaces along the imaginary phonon modes and by using the climbing-image nudged elastic-band method.
