Summary: In this study, SnSe/SnSe2 heterostructure composites with polypyrrole (PPy) coating layer and selenium (Se) vacancies were successfully prepared as anode materials for lithium-ion batteries (LIBs) and sodium-ion batteries (SIBs). The results showed that the PPy coating layer, SnSe and SnSe2 heterostructure, and Se vacancies all contributed positively to the performance of the materials. Furthermore, by adjusting the ratio of SnSe and SnSe2, the Sn3Se5@PPy composite with the best performance was obtained.

Summary: Phosphorus composite anodes are considered promising candidates for sodium-ion batteries and potassium-ion batteries, but their practical use is limited by poor cycling stability and sluggish electrochemical reaction dynamics caused by volume variation and low electronic conductivity. Compositing with a suitable second component has been proposed as an effective strategy to potentially resolve these issues.

Summary: We investigated the electrochemical performance of 5% Al doped MoS2@rGO composite as an anode for sodium-ion batteries. The results showed that Al doping increased the interlayer spacing of MoS2 nanosheets and formed a stable 1T phase. The composite exhibited stable specific capacity and high capacity retention over 200 cycles, with a consistent Coulombic efficiency of nearly 100%. The kinetics and diffusion coefficient of the electrode were analyzed using various techniques, and the stable morphology of the composite was confirmed after 500 cycles. The sodium-ion transport properties of the composite were also calculated using density functional theory.

Summary: This study investigates the electrochemical and transformation behavior of three alloy materials (antimony, silicon, and tin) and finds that antimony is particularly well suited for low-temperature applications, offering ten times higher specific capacity than graphite on the first cycle. The study examines the kinetic and thermodynamic limitations of these materials at low temperatures using various techniques, including the galvanostatic intermittent titration technique and X-ray diffraction. The use of reference electrodes is also found to be necessary at low temperatures.
