Chalcogenides have attracted great attention as functional materials in optics, electronics, and energy-related applications due to their typical semiconductor properties. Among those chalcogenides, Sb2S3 holds great promise in energy storage field, especially as an anode material for alkali metal (Li, Na, and K) batteries. In this work, a one-dimensional coaxial Sb2S3@PPy is investigated as a versatile and robust anode in three kinds of alkali metal batteries for the first time, and the energy storage mechanism of these batteries is systematically discussed. As an anode material for sodium ion batteries (SIBs) and potassium ion batteries (KIBs), Sb2S3@PPy exhibits high reversible capacity and impressive cycle lifespan. Sb2S3@PPy anode demonstrates an adsorption behavior that has a significant influence on its sodium storage behavior, providing a universal model for studying the application of chalcogenide compounds.

AbstractSearching for advanced anode materials with excellent electrochemical properties in sodium-ion battery is essential and imperative for next-generation energy storage system to solve the energy shortage problem. In this work, two-dimensional (2D) ultrathin FePS3 nanosheets, a typical ternary metal phosphosulfide, are first prepared by ultrasonic exfoliation. The novel 2D/2D heterojunction of FePS3 nanosheets@MXene composite is then successfully synthesized by in situ mixing ultrathin MXene nanosheets with FePS3 nanosheets. The resultant FePS3 nanosheets@MXene hybrids can increase the electronic conductivity and specific surface area, assuring excellent surface and interfacial charge transfer abilities. Furthermore, the unique heterojunction endows FePS3 nanosheets@MXene composite to promote the diffusion of Na+ and alleviate the drastic change in volume in the cyclic process, enhancing the sodium storage capability. Consequently, the few-layered FePS3 nanosheets uniformly coated by ultrathin MXene provide an exceptional reversible capacity of 676.1 mAh g−1 at the current of 100 mA g−1 after 90 cycles, which is equivalent to around 90.6% of the second-cycle capacity (746.4 mAh g−1). This work provides an original protocol for constructing 2D/2D material and demonstrates the FePS3@MXene composite as a potential anode material with excellent property for sodium-ion batteries.

<p>In this work, we apply an amine-assisted silica pillaring method to create the first example of a porous Mo<sub>2</sub>TiC<sub>2 </sub>MXene with nanoengineered interlayer distances. The pillared Mo<sub>2</sub>TiC<sub>2</sub> has a surface area of 202 m<sup>2</sup> g<sup>-1</sup>, which is among the highest reported for any MXene, and has a variable gallery height between 0.7 and 3 nm. The expanded interlayer distance leads to significantly enhanced cycling performance for Li-ion storage, with superior capacities, rate capabilities and cycling stabilities in comparison to the non-pillared version. The pillared Mo<sub>2</sub>TiC<sub>2</sub> achieved capacities over 1.7 times greater than multilayered MXene at 20 mA g<sup>-1</sup> (≈ 320 mAh g<sup>-1</sup>) and 2.5 times higher at 1 A g<sup>-1</sup> (≈ 150 mAh g<sup>-1</sup>). The fast-charging properties of pillared Mo<sub>2</sub>TiC<sub>2</sub> are further demonstrated by outstanding stability even at 1 A g<sup>-1</sup> (under 8 min charge time), retaining 80% of the initial capacity after 500 cycles. Furthermore, we use a combination of spectroscopic techniques (i.e. XPS, NMR and Raman) to show unambiguously that the charge storage mechanism of this MXene occurs by a conversion reaction through the formation of Li<sub>2</sub>O. This reaction increases by 2-fold the capacity beyond intercalation, and therefore, its understanding is crucial for further development of this family of compounds. In addition, we also investigate for the first time the sodium storage properties of the pillared and non-pillared Mo<sub>2</sub>TiC<sub>2</sub>.</p>
