Summary: Composite-polymer-electrolytes (CPEs) embedded with an unsaturated coordination Prussian blue analog (UCPBA) filler demonstrate fast and preferential Li+ conduction through a chemically stable electrolyte/filler interface (EFI). The unsaturated Co-O coordination in UCPBA ensures a stable EFI and prevents side reactions, while the Lewis-acid metal centers attract the Lewis-base anions of Li salts, enhancing Li+ disassociation and transference number (tLi+). These CPEs exhibit high room-temperature ionic conductivity and excellent cyclability and capacity retention for solid-state lithium-sulfur batteries.

Summary: In this study, an aqueous Sn-Mn full battery was established in acidic electrolytes by utilizing a Sn anode with high deposition efficiency and stability, and a stabilized Mn2+/Mn3+ redox couple in the cathode. The reversible conversion between Mn2+ and Mn3+ ions was achieved on the graphite surface through the help of H+ and a complexing agent. A protective layer formed by a pyrophosphate ligand effectively prevented Mn3+ from disproportionation and uncontrolled diffusion. The designed battery demonstrated excellent electrochemical performance, including a large capacity, high discharge plateau voltage, excellent rate capability, and superior cycling stability.

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: Due to their high abundance, low cost, and high safety, zinc-based batteries offer promising opportunities for large-scale energy storage. However, the stability, lifetime, and reversibility of these batteries are affected by passivation and dendrite growth on the zinc anode. In this study, the researchers introduced an iodine post-functionalized zeolitic imidazolate framework-90 (ZIF-90-I) additive to address this challenge. The additive was able to regulate the formation of the solid-electrolyte interphase (SEI) and promote uniform deposition of Zn2+ ions, while the I-3(-)/I- redox reaction rejuvenated the dead Zn and inhibited dendrite growth. The results showed improved cycling stability and high utilization rate of the zinc anode.
