Summary: A topotactic epitaxy process was proposed to generate K2Mn[Fe(CN)(6)] (KMF) submicron octahedra and assemble them into octahedral superstructures (OSs) as the SIB cathode. The self-assembly behavior of KMF improves the structural stability and decreases the contact area with the electrolyte, which inhibits the transition metal dissolution. Furthermore, KMF acts as a stabilizer to disrupt the long-range JT order of NMF, thereby suppressing the overall JT distortion. As a result, KMF cathodes exhibit excellent electrochemical performances with highly reversible phase transition and outstanding cycling performance.

Summary: Understanding irreversible and reversible sorption in sediment is crucial for predicting the fate and transport of contaminants in surface waters. This study demonstrated the irreversible accumulation and reversible absorption of perfluoroalkyl acids in sediment from an urban water body. The results suggest that sediment can act as a sink for the studied contaminants and rubbery SOC may act as a concentration buffer. The S-D cycling can increase the irreversible absorption concentration, even at lower exposure concentrations, and the log KOC values of the sediment overlap with field data.

Summary: In this study, FeS micro-flakes were successfully synthesized and showed good stability and dispersibility in water, leading to high efficiency in removing Hg(II). The sorption of Hg(II) on FeS micro-flakes was consistent with the pseudo-second-order kinetic model and Langmuir model, indicating monolayer sorption dominated by chemical sorption. The maximum sorption capacity was significantly higher than FeS nanoparticles and other Hg(II) scavengers. FeS (0.31 g/L) effectively removed >97.6% of 200 mg/L Hg(II) in the pH range of 2-12 at 30 degrees C. The removal mechanism involves chemical precipitation and surface adsorption. This study demonstrates the potential and viability of FeS micro-flakes for efficiently removing aqueous Hg(II).

Summary: The electronic structure of transition metal-doped NiFe2O4(0 0 1) surface was studied to investigate its effect on the intrinsic activity of oxygen evolution reaction (OER). The variation of Fe oxidation states was found to originate from the super-exchange effect and the t2g-electron configuration of 3d metal dopants. This trend governs the generation of highly-active Fe3+ sites and the adsorption strength of OER intermediates, providing insights into electronic structure tailoring strategies for improving the intrinsic activity of OER electrocatalysts.

Summary: Comprehensive analyses of thermal runaway mechanisms are crucial for the safe operation of lithium-sulfur (Li-S) batteries. The thermal runaway of 1.0 Ah cycled Li-S pouch cells is attributed to the reactions between dissolved higher-order polysulfides and Li metal. Adding electrolyte significantly affects the thermal safety, with the 16-cycle pouch cell experiencing severe thermal runaway while the 45-cycle pouch cell remains stable. The presence of high-order polysulfides (Li2Sx > 6) and exothermic reactions with cycled Li contribute to the thermal runaway of Li-S pouch cells.

Summary: The stability of lithium metal anodes crucially determines the lifespan of high-energy-density lithium metal batteries. Traditional additive lithium nitrate (LiNO3) forms LiNxOy-containing solid electrolyte interphase (SEI) to stabilize lithium metal anodes, but its poor solubility in ester electrolytes hinders its application. In this study, organic nitrate isosorbide nitrate (ISDN) is proposed as a replacement for LiNO3. ISDN exhibits high solubility in ester electrolytes due to the introduction of organic segments, enabling the formation of LiNxOy-rich SEI and promoting uniform lithium deposition. The lifespan of lithium metal batteries is significantly extended from 80 to 155 cycles with the use of ISDN under demanding conditions. Furthermore, a lithium metal pouch cell with an energy density of 439 Wh kg(-1) delivers 50 cycles. This work opens up a new pathway for developing practical additives for lithium metal batteries through molecular modifications.

Summary: This study proposes an integrated interface configuration (IIC) for all-solid-state lithium metal batteries (ASSLMBs) to regulate interface transport kinetics and inhibit lithium dendrite growth. The IIC consists of in-situ generated LiI interphase and Li-Ag alloy anode, which can achieve uniform lithium platting and stabilize the lithium/electrolyte interface. The Li||Li symmetric cells with IIC demonstrate a critical current density of 1.6 mA cm-2 and stable cycling over 1600 hours at a high current density of 0.5 mA cm-2. Moreover, a high discharge capacity of 140.1 mA h g-1 at 0.1 C is obtained for the Li (Ni0.6Co0.2Mn0.2)O2 (NCM622) full battery with a capacity retention of 65.6% after 300 cycles.
