Summary: This study presents a novel additive design principle to enhance the reversible and dendrite-free zinc anode in aqueous batteries. By introducing Dibenzene-sulfonamide (BBI) into ZnSO4 electrolyte, BBI-derivate is preferentially chemisorbed on Zn surface to protect against corrosion and suppress hydroxide sulfate formation. Furthermore, the decomposition of BBI leads to the in-situ construction of a robust organic-inorganic hybrid solid electrolyte interphase on Zn anode, which regulates the Zn-anode interfacial chemistry to enable uniform Zn deposition. Consequently, the Zn symmetric cells exhibit prolonged cycling lifespan and high capacity. This study provides insights into the additive regulation mechanisms and offers a promising approach to solve the anode nuisance in aqueous metal batteries.

Summary: The research addresses the insufficient stability of the electrolyte towards oxidation in high-voltage lithium-ion cathode materials, and introduces a new combination of electrolyte additives to improve battery performance. The synergistic effect of TTSPi and TFEC additives significantly enhances cycling stability, capacity, and coulombic efficiency in lithium-ion cells with a voltage higher than 4.5 V, which can be further improved with the addition of lithium bis(oxalato)borate.

Summary: By adding small concentrations of multivalent salts into the baseline electrolyte, silicon anodes with superior calendar life can be developed. The Ca additive reacts with F ions in the electrolyte to form a strong and dense layer of nanocrystalline CaF2, effectively protecting the silicon core from side reactions. This approach is universally effective for all available commercial silicon or SiO sources.

Summary: In this study, FeF2 nanoparticles were embedded in an interconnected cPAN network to passivate the cathode/electrolyte interface. The cPAN acted as a superior binder and effectively inhibited the growth of excessive CEI. DFT calculations showed that cPAN was inert to the electrolyte and suppressed the catastrophic decomposition caused by FeF2.

Summary: Researchers have discovered that adding trace amounts of perfluorooctanoic acid (PFOA) to aqueous zinc-ion batteries (AZIBs) can effectively address issues such as side reactions and poor performance. The PFOA additives reduce the surface tension of electrolytes and improve the wettability of electrolytes on the electrode, thereby enhancing the electrochemical stability and lifespan of the battery.

Summary: An emerging development direction for electrolytes is the utilization of low-concentration electrolytes (LCE) due to their promising properties such as better wetting ability, reduced costs, and fast electrochemical kinetics. However, the direct assessment of LCEs with Li metal anodes has not been done, which could provide new insights to high-energy-density rechargeable LMBs.

Summary: Film-forming electrolyte additives have a significant impact on the interfacial chemistries and practical performances of LiCoO2-based lithium-ion batteries. In this study, the effects of four typical additives, including vinylene carbonate (VC), 1,3-propane sultone (PS), fluoroethylene carbonate (FEC), and adiponitrile (ADN), on the discharge capacities and stabilities of LiCoO2-based batteries at different temperatures were evaluated. The results reveal that these additives can influence the performance of the batteries by adjusting the morphologies and protection effects of the cathode/electrolyte interphase (CEI) films.

Summary: Solid oxide fuel cell (SOFC) technology provides reliable and efficient power generation through electrochemical oxidation of fuel gases. Current nickel-based anodes are prone to poisoning by sulfur and other fuel impurities. In this study, we investigated the performance and sulfur tolerance of electrolyte supported cells with infiltrated anodes tested under real-life conditions. The results showed that the cells with non-noble electrocatalysts infiltrated anodes exhibited similar initial performance to the state-of-the-art cells with nickel/ceria-gadolinium oxide (CGO) cermet anodes, but with lower performance loss when the desulfurization unit was bypassed. Additionally, the cells with infiltrated anodes showed almost complete recovery of performance after stopping the exposure to sulfur, indicating their potential as next-generation SOFC materials.
