Summary: Rechargeable aqueous Zn-MnO2 batteries are promising for large-scale energy storage, but the issues of phase transition and structural collapse of MnO2 cathodes still exist. Intercalation of layered MnO2 has become the mainstream strategy, but the characteristics of Mn octahedral layers are often neglected. In this study, the researchers elucidate the impact of layer symmetry on the electrochemical performance of birnessites. The hexagonal birnessite with stabilized Mn(II) ions exhibits better charge storage performance than its monoclinic precursor, due to the generation of layer cation vacancies, interlayer Mn(II) ions, and nanosized morphology. The work provides a new approach for designing high-performance layered cathode materials.

Summary: In this study, a facile strategy of anion engineering was proposed to improve the bifunctionality of layered LiCoO2 (LCO) for Zn-air batteries (ZABs). Partial substitution of fluorine for oxygen induced oxygen vacancies and modulated the electronic structure of Co, thereby accelerating oxygen electrocatalysis kinetics. The potential gap (Delta E) between the OER potential and ORR potential of LiCoO1.8F0.2 (LCOF0.2) catalyst (0.986 V) was significantly lower than that of pristine LCO catalyst (1.162 V), indicating a higher bifunctional activity. The ZABs using LCOF0.2 as the air electrode exhibited a peak power density of 193 mW cm-2, which was 1.53-fold higher than that of the LCO-based ZABs. This study demonstrates the feasibility of F doping to improve the bifunctional electrocatalytic performance of LiCoO2.

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: 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: Electrolyte environments, including cations, anions, and solvents, play a critical role in the performance of battery cathodes. However, most research has focused on the interaction between cations and cathode materials, neglecting the correlation between anions and cathodes. This study systematically investigates how anions influence the coulombic efficiency (CE) of zinc battery cathodes, demonstrating that the electronic properties of anions can tune conversion or intercalation reactions, resulting in significant differences in CE.

Summary: In this study, an all-active solid interhalogen compound, IBr, is reported as a cathode material to address the challenges caused by the highly soluble Br-2/Br-3(-) species. By fixing the oxidized Br-0 with iodine (I), the cross-diffusing Br-2/Br-3(-) species during the charging and discharging process are eliminated. The Zn||IBr battery exhibits a remarkably high energy density of 385.8 Wh kg(-1), surpassing that of I-2, MEMBr3, and TPABr(3) cathodes. This work provides new approaches for achieving active solid interhalogen chemistry in high-energy electrochemical energy storage devices.

Summary: Constructing a reliable solid-electrolyte interphase (SEI) plays a vital role in achieving highly reversible zinc metal (Zn-0) electrodes. Instead of the traditional bulk solvation mechanism, this study reveals that the structure of SEI is mainly influenced by electric double layer (EDL) adsorption. By manipulating the EDL adsorption and Zn2+ solvation using ether additives, a layer-structured SEI with high rigidity and toughness is formed, leading to improved performance of the zinc metal electrodes.

Summary: Transition metal-nitrogen-carbon materials, particularly Fe-N-C, have been found to be electroactive for accelerating the oxygen reduction reaction (ORR) kinetics. However, their performance is still unsatisfactory despite efforts to enhance their active species content, surface area, and electronic conductivity. This study introduces Ti3C2 MXene with sulfur terminals to regulate the electronic configuration of FeN4 species and significantly enhance the catalytic activity toward ORR. The results demonstrate that the regulation of the electronic structure of active species via coupling with their support can greatly enhance their catalytic activity.
