Summary: A convenient and efficient strategy is proposed to construct a Li3N-based interlayer between solid poly(ethylene oxide) (PEO) electrolyte and Li anode by in situ thermal decomposition of 2,2 '-azobisisobutyronitrile (AIBN) additive. The Li3N nanoparticles evolved from the decomposition can combine with LiF, cyano derivatives, and PEO electrolyte to form a buffer layer during the cell cycle, which improves the stability and homogeneity of Li deposition. The Li||Li symmetric cells with Li3N-based interlayer exhibit excellent cycle stability, with a cycle life at least 4 times longer than that of PEO electrolytes without Li3N layer. This work provides a convenient strategy for interface engineering in solid-state polymer electrolyte and Li anode.

Summary: Metal solid-state batteries are considered the next-generation energy storage systems with high energy density and high safety. A strong and intimate solid-state interfacial contact between sodium metal and solid-state electrolyte is crucial for good cyclic stability at high current density. Inorganic electrolytes suffer from poor stability when cycled at low current density, leading to dendrite formation and loss of solid-solid contact at the interface. Further research and engineering approaches are needed to improve the integration of sodium metal with solid-state electrolytes and enhance electrochemical performance.

Summary: By designing an aqueous electrolyte with a weakly solvating effect, a durable anion-derived solid electrolyte interface (SEI) with high ion conduction properties is constructed, which significantly restrains dendrite formation and adverse reactions on the Zn anode surface, leading to high reversibility of deposition/stripping, ultra-long lifespan over 5000 h, and exceptional cumulative capacity. The formation mechanism of SEI and the composition distribution of anion-derived inorganic-rich SEI are clarified in detail. Furthermore, the Zn//Prussian blue analogue (PBA) full battery exhibits a high voltage platform of 2.1 V and delivers 99.3% capacity retention after 5000 cycles, benefiting from the synergy of the elaborate SEI and regulated electrolyte environment.

Summary: Calcium ion batteries (CIBs) are potential energy storage devices due to their abundant resources and low cost. However, slow kinetics limit their performance. In this study, a solvation regulation strategy based on donor number (DN) was proposed to enhance the storage of Ca2+ in sodium vanadate (NVO) cathode. The use of solvent with low DN facilitated the migration of Ca2+ and promoted the insertion of Ca2+ into the NVO electrode, resulting in high capacity and high-rate performance.

Summary: This study aimed to investigate the potential mechanisms by which probiotics reduce carbon quantum dots (CQDs) neurotoxicity from a brain-gut axis perspective by exposing carp to CQDs and/or probiotics for five weeks. The results showed that CQDs accumulation in the brain reduces the expression of blood-brain-barrier (BBB) related genes in carp, leading to brain damage. In addition, CQDs impaired motor behavior and inhibited acetylcholinesterase activity. These abnormalities were alleviated by probiotic supplementation.

Summary: Aqueous iron batteries have the potential for large-scale energy storage due to their safety and low cost. However, their long-term cycling stability is inadequate. In this study, cross-linked polyaniline (C-PANI) is proposed as a positive electrode active material to improve the electronical conductivity and electrochemical stability. The C-PANI, when combined with Fe metal negative electrode and Fe(TOF)(2) electrolyte, shows good specific capacity and discharge voltage after a high number of cycles. Mechanistic studies suggest that the bonding of Fe2+ ions to TOF- anions plays a role in the storage of charge.

Summary: Advanced electrolyte engineering plays a crucial role in developing high-efficiency lithium metal batteries, but the current electrolytes have limitations in performance over different temperature ranges. In this study, a new electrolyte design utilizing fluorosulfonyl carboxylate as a non-solvating solvent is introduced to achieve high-performance and temperature-tolerant lithium metal batteries. The optimized electrolyte enables favorable chemistry on both the lithium metal anode and nickel-rich cathode, resulting in enhanced lithium ion transfer kinetics, dendrite-free lithium deposition, and suppressed electrolyte degradation. These improvements lead to a long cycling lifespan and superior capacity retention of the batteries under various cycling conditions at different temperatures. Moreover, this electrolyte expands the operating temperature range and significantly improves the battery's capacity retention and Coulombic efficiency at high temperature. Therefore, fluorosulfonyl carboxylates show great potential for use in high-performance and all-weather lithium metal batteries, further advancing electrolyte design.

Summary: High-entropy alloys/compounds with increased configurational entropy exhibit improved functional properties compared to conventional materials. In this study, the impact of increasing entropy in liquid electrolytes for rechargeable lithium batteries was demonstrated. The introduction of multiple salts in the electrolyte induced a larger diversity in solvation structures, enhancing lithium-ion diffusivity and the formation of stable interphase passivation layers. A low-concentration dimethyl ether electrolyte with four salts showed enhanced cycling stability and rate capability. These findings highlight the potential of high-entropy electrolytes for lithium batteries and beyond.

Summary: This study demonstrates the improvement of mechanical properties and reduction of coefficient of thermal expansion (CTE) in graphene oxide (GO)/epoxy (EP) nanocomposites by enhancing the interface between GO and EP through functionalization and incorporating rigid-flexible interphases. The results reveal that the SiO2-PEA-GO hybrid exhibits better strengthening and toughening effects, as well as lower CTE, compared to the PEA-GO hybrid due to the presence of rigid-flexible interfaces with higher bonding strength and better energy dissipation mechanisms. Additionally, the nanocomposites with longer polyetheramine (PEA) molecules in the rigid-flexible interphases demonstrate higher strength and toughness, while maintaining a lower CTE. This work provides a promising strategy for constructing adjustable flexible-rigid interfacial structures and offers potential in developing GO/EP nanocomposites with high mechanical properties and low CTE.
