Summary: By in-situ growing a Zn-TPA-MOF/ZnO hybrid interface protection layer on pre-oxidized Zn foil surface, the side reactions and dendrite growth of Zn anodes can be suppressed, leading to improved reversibility. The hybrid protection film exhibits high ionic conductivity and low electrical conductivity, which can efficiently accelerate the interface transfer of zinc ions. The results demonstrate that the Zn anode with the hybrid protection film has a significantly longer cycling life and higher Coulombic efficiency compared to traditional Zn anodes.

Summary: This study introduces TEMPO-oxidized nanofibrillated cellulose (ONFC) with charged carboxyl groups for the efficient exfoliation of two-dimensional MoS2/graphene composites. With the assistance of ONFC, the exfoliated MoS2/graphene increases gradually in the aqueous dispersions. Self-standing flexible films of MoS2/graphene/ONFC/CNTs are constructed using ONFC as a fibrous skeleton and CNTs/graphene as an electrical network. The electrode materials based on natural cellulose show potential for green electronics with high flexibility and increased portability.

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: A highly effective solid-electrolyte interphase (SEI) for improving the reversibility of the Zn metal anode (ZMA) was constructed using a bisolvent electrolyte, and its composition/structure was resolved by cryogenic transmission electron microscopy. The resulting SEI is highly fluorinated with amorphous inorganic ZnFx uniformly distributed in the organic matrix, which is different from common mosaic and multilayer SEIs with crystalline inorganics. This SEI exhibits improved structural integrity, mechanical toughness, and Zn2+ ion conductivity, leading to excellent reversibility of the ZMA.

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.

Summary: This study demonstrates that the adoption of an OH-rich hydrogel electrolyte can effectively activate the redox site of the KFeMnHCF cathode and improve its structural stability, addressing the limitations of small capacities and short lifespans in PBA cathode materials. Furthermore, the strong adhesion of the hydrogel electrolyte prevents KFeMnHCF particles from falling off and dissolving. The desolvation of metal ions in the OH-rich hydrogel electrolytes enables fast and reversible intercalation/deintercalation in the PBA cathode, leading to unprecedented characteristics in Zn||KFeMnHCF hybrid batteries.
