Summary: Li+-intercalated SnS2 with expanded interlayer spacing (0.89 nm) was prepared by the one-step urothermal method as a promising anode material for Li-ion batteries. Compared with pure SnS2, the Li+-intercalated SnS2 electrode exhibits higher initial Coulombic efficiency (79.3% vs 55%), better rate performance (548.4 mAh g(-1)at 2 A g(-1)and 216.6 mAh g(-1)at 10 A g(-1)), and improved cycling performance (647.7 mAh g(-1) at 0.1 A g(-1)after 100 cycles).

Summary: We report the conversion of bulk Li alloying anode reactions into surface reactions by encapsulating amorphous structured SnSx active materials in carbon nanofiber anodes. The high-temperature phase transformation from SnS to SnS2 is utilized to construct the SnSx (1 < x < 2) active material with an amorphous structure, resulting in decreased Li+ diffusion path, weakened volume change ratio, but enhanced capacitance. The amorphous structure changes the Li-storage mechanism from intercalation to surface reaction, enabling rapid (de)lithiation of each active particle. As a result, SnSx@NC exhibits high-rate (dis)charge performance and long-term cycle life, achieving an excellent rate capability of 633.4 mAh g-1 under 7 A g-1 and a capacity retention of 785.2 mAh g-1 after 1600 cycles under 2 A g-1.

Summary: A simple and green method was proposed for the synthesis of SnS2/NC nanosheets, and its evolution mechanism and electronic conductivity were investigated. The results showed improved electronic conductivity and Li adsorption affinity after N doping in SnS2/NC material. Benefitting from these enhancements, the SnS2/NC anode achieved satisfactory discharge capacity (863.9 mAh/g at 100 mA/g over 100 cycles) and the full cell exhibited a low capacity attenuation (0.3% per cycle over 90 cycles). The sequential evolution mechanism of intercalation, conversion, and alloying reactions during lithiation was revealed through in-situ XRD, ex-situ XPS, and NMR characterizations. These findings provide significant reference and guideline for the evolution mechanism of other metal sulfides materials in energy storage applications.

Summary: SnS and SnS2 are two anode materials with excellent theoretical capacity for Sodium ion batteries. However, their electrochemical performance is affected by volume collapse and low electric charge conductivity. The construction of SnS-SnS2 heterostructures improves conductivity, and compounding with Graphene Oxide (GO) prevents volume effects and enhances cyclic stability and initial coulombic efficiency. Experimental and simulation studies show that SnS-SnS2 @GO composites exhibit superior conductivity, cycle stability, and unique nano-flake structure, making them ideal anode materials for sodium ion batteries.

Summary: A three-dimensional (3D) structure of SnS2 with sulfur vacancies (S-SnS2) anchored on the surface of reduced graphene oxide (rGO) was synthesized. The addition of glycolic acid promoted the bonding of SnS2 with rGO and enabled the generation of sulfur vacancies. The unique 3D structure facilitated lithium-ion diffusion and the S/N-doped rGO (NSG) enhanced the electronic conductivity of the S-SnS2/NSG. As a result, the S-SnS2/NSG exhibited a high capacity and ultrastable long cycling performance in lithium-ion batteries.

Summary: Potassium (K) metal batteries have potential for commercial development, but the arbitrary dendrite growth and side reactions of K metal hinder their progress. Interface engineering between the current collector and K metal can improve the performance by guiding K metal deposition and suppressing side reactions. A bifunctional layer with an O/F-rich Sn-K alloy and a preformed solid-electrolyte interphase (SEI) layer has been designed to achieve this. The bifunctional layers enable low nucleation overpotential, high Coulombic efficiency, and stable operation of K metal batteries.

Summary: Lithium-sulfur batteries (LSBs) are a promising next-generation electrochemical energy storage system with high theoretical specific capacity and low cost. However, the shuttling effect of soluble polysulfides has hindered their commercial applications. In this study, tin disulfide nanosheets were anchored on nitrogen-doped hollow carbon to form a bipolar dynamic host (SnS2@NHCS), effectively confining the polysulfides and promoting their conversion. The assembled LSBs exhibited high capacity, superior rate, and cyclability. This work provides new insights for the development of novel composite electrode materials for rechargeable batteries with emerging applications.

Summary: The use of tin dioxide as an anode for lithium and sodium ion batteries is hindered by low conductivity and tin coarsening issues. This study presents a robust strategy to enhance electrochemical performance and understand the energy storage mechanism of SnO2 by crafting poly(ethylene glycol)-ligated SnO2 nanoparticles and confining them in a layer-by-layer stacked graphene oxide matrix. The resulting nanohybrids exhibit a high discharge capacity and stable sodium storage capacity, while also inhibiting tin coarsening and promoting ion and electron transfers.
