Summary: The crossover of transition-metal ions has minimal effect on the lithium-metal anode in batteries with high-nickel layered-oxide cathodes, but the soluble decomposition products from the anode adversely impact the cathode, accelerating impedance growth and capacity fade. This study highlights the importance of improved battery design for lithium-metal anodes to address these crossover effects.

Summary: This study systematically investigates the localized high-concentration electrolytes (LHCEs) using different fluorinated diluents, calculating their physical properties and activation energies for reactions with singlet oxygen (O-1(2)), and comparing the electrochemical performances of LOBs using these electrolytes. The research reveals that the stability of the electrolytes is strongly correlated with their physical and electrochemical properties depending on the diluents in LHCEs, shedding light on the rational design of new electrolytes for LOBs.

Summary: Conventional LiPF6/carbonate-based electrolytes have been widely used in graphite-based lithium ion batteries for their stability, but are less stable in Li metal and silicon anodes. Localized high-concentration electrolytes have unique advantages, forming stable SEI layers to improve stability.

Summary: A novel electrolyte has been proposed in this study to effectively eliminate the shuttle effect in lithium-sulfur batteries, resulting in stable cycling performance. By utilizing a solid-phase reaction route and forming a compact cathode electrolyte interface film, the developed strategy shows promise for future development of Li-S batteries based on solid-phase conversion.

Summary: This study investigates the impact of in situ deposited transition metal (TM) ions on silicon-based anodes and the individual influences of nickel (Ni), manganese (Mn), and cobalt (Co) on the structural and electrochemical stability. The results show that TM ion dissolution has a greater effect on silicon than on graphite, and different TM ions exhibit different influences on anode-electrolyte interphase formation.

Summary: In this study, localized electrolytes based on fluorinated ethers with a total salt concentration of only 0.1 M were investigated for their performance in Li-S batteries. These electrolytes were found to suppress the formation of long-chain polysulfides, limit sulfur cathode dissolution, and improve active material utilization, leading to higher capacity and coulombic efficiency compared to traditional electrolyte solvent mixtures.

Summary: This study used operando nuclear magnetic resonance (NMR) spectroscopy to observe electrolyte decomposition and investigate the influence of individual components on the performance of localized high concentration electrolytes (LHCEs) in lithium metal batteries. The results suggest that the diluent molecules in LHCEs play a critical role in the formation of solid electrolyte interphase (SEI). Three-electrode electrochemical impedance spectroscopy (EIS) showed different interfacial resistances between LHCE and standard high concentration electrolytes (HCEs), which can be attributed to the incorporation of diluent reaction products into the SEI.

Summary: By diluting high-concentration ether electrolytes with a non-solvating fluorinated ether, the research team successfully regulated the formation/evolution of solid electrolyte interphases (SEI) on phosphorus/carbon (P/C) anodes. This resulted in improved electrode performance, including reversible capacity, capacity retention rate, and rate capability. This research provides important insights for the development of high-performance potassium-ion batteries.
