Summary: Siligraphene, a combination of monolayer silicon and monolayer carbon, is a promising anode material for potassium ion batteries, with high stability, high capacity, fast ion diffusion, and excellent electrical conductivity. The theoretical capacity and average voltage of g-SiC5 and g-Si2C4 for KIB are 304.1 mA h/g and 128.6 mA h/g, about 0.4 V and 0.3 V respectively. NEB calculations show low energy barriers for potassium ion diffusion on siligraphene, indicating a high migration rate. Additionally, bandstructure calculations demonstrate excellent electrical conductivity after potassium ion absorption, and MD calculations confirm good stability of siligraphene with absorbed potassium ions.

Summary: This study explores high-capacity and efficient anode materials for rechargeable lithium-ion batteries. It is found that borophene and phosphorene can form stable heterojunctions with good conductivity. The theoretical capacity of these heterojunctions is high, and the average voltage is greatly reduced compared to bare phosphorene. Therefore, the B/P heterojunction shows great potential for application.

Summary: Finding efficient electrode materials with excellent electrochemical performance is crucial for the development of magnesium-ion batteries (MIBs). Two-dimensional Ti-based material, TiClO monolayer, shows promising potential as an anode for MIBs due to its high storage capacity, low energy barrier, and suitable open-circuit voltage. Furthermore, bilayer and trilayer TiClO can enhance the Mg binding strength and maintain the quasi-one-dimensional diffusion feature compared to monolayer TiClO, making it an even more favorable candidate for MIBs.

Summary: Potassium ion batteries (PIBs) are attractive due to abundant potassium resources, low cost, and high potential. However, the larger radius of K+ compared to Na+/Li+, poor kinetics, and unstable structure result in inferior electrochemical performance. In this study, a 3D fluorine-doped carbon@Ti3C2 MXene (3D FC@Ti3C2) composite is proposed as an anode material for PIBs. The composite exhibits enhanced electrochemical properties, including high capacity and cyclic stability, attributed to the protective carbon coating, fluorine-doped carbon with more defects and active sites, enlarged interlayer spacing, and the 3D interconnected carbon framework.

Summary: Nanosized sodium sulfide species greatly enhance the performance of Na-S batteries, but the diminished stability with decreasing cluster size has been rarely considered. This study presents a binary phase diagram of sodium sulfide clusters (NSCs) using an advanced structure search algorithm. The commonly studied monomer model with low sulfur concentrations is energetically unfavorable, thus aggregation of monomers to form multimers is necessary. The relatively stable clusters with low sulfur concentrations, as well as their interaction with carbon-based substrates, are investigated. The findings provide insights into the evolution mechanism of NSCs and the development of high-performance Na-S batteries.
