Prussian blue analogs (PBAs) are promising insertion‐type cathode materials for different types of aqueous batteries, capable of accommodating metal or non‐metal ions. However, their practical application is hindered by their susceptibility to dissolution, which leads to a shortened lifespan. Herein, we have revealed that the dissolution of PBAs primarily originates from the locally elevated pH of electrolytes, which is caused by the proton co‐insertion during discharge. To address this issue, the water‐locking strategy has been implemented, which interrupts the generation and Grotthuss diffusion of protons by breaking the well‐connected hydrogen bonding network in aqueous electrolytes. As a result, the hybrid electrolyte enables the iron hexacyanoferrate to endure over 1000 cycles at a 1 C rate and supports a high‐voltage pH‐decoupled cell with an average voltage of 1.95 V. These findings provide insights for mitigating the dissolution of electrode materials, thereby enhancing the viability and performance of aqueous batteries. [ABSTRACT FROM AUTHOR]

In the pursuit of next‐generation ultrahigh‐energy‐density Li−O2 batteries, it is imperative to develop an electrolyte with stability against the strong oxidation environments. N,N‐dimethylacetamide (DMA) is a recognized solvent known for its robust resistance to the highly reactive reduced oxygen species, yet its application in Li−O2 batteries has been constrained due to its poor compatibility with the Li metal anode. In this study, a rationally selected hydrofluoroether diluent, methyl nonafluorobutyl ether (M3), has been introduced into the DMA‐based electrolyte to construct a localized high concentration electrolyte. The stable −CH3 and C−F bonds within the M3 structure could not only augment the fundamental properties of the electrolyte but also fortify its resilience against attacks from O2− and 1O2. Additionally, the strong electron‐withdrawing groups (−F) presented in the M3 diluent could facilitate coordination with the electron‐donating groups (−CH3) in the DMA solvent. This intermolecular interaction promotes more alignments of Li+‐anions with a small amount of M3 addition, leading to the construction of an anion‐derived inorganic‐rich SEI that enhances the stability of the Li anode. As a result, the Li−O2 batteries with the DMA/M3 electrolyte exhibit superior cycling performance at both 30 °C (359th) and −10 °C (120th). [ABSTRACT FROM AUTHOR]

The surrounding hydrogen bond (H‐bond) interaction around the active sites plays indispensable functions in enabling the organic electrode materials (OEMs) to fulfill their roles as ion reservoirs in aqueous zinc‐organic batteries (ZOBs). Despite important, there are still no works could fully shed its real effects light on. Herein, quinone‐based small molecules with a H‐bond evolution model has been rationally selected to disclose the regulation and equilibration of H‐bond interaction between OEMs, and OEM and the electrolyte. It has been found that only a suitable H‐bond interaction could make the OEMs fully liberate their potential performance. Accordingly, the 2,5‐diaminocyclohexa‐2,5‐diene‐1,4‐dione (DABQ) with elaborately designed H‐bond structure exhibits a capacity of 193.3 mAh g−1 at a record‐high mass loading of 66.2 mg cm−2 and 100 % capacity retention after 1500 cycles at 5 A g−1. In addition, the DABQ//Zn battery also possesses air‐rechargeable ability by utilizing the chemistry redox of proton. Our results put forward a specific pathway to precise utilization of H‐bond to liberate the performance of OEMs. [ABSTRACT FROM AUTHOR]

[Objectives] To clarify the effect of density on the population growth of Phenacoccus solenopsis to improve control of this pest. [Methods] The development and reproduction of P. solenopsis kept at (26 ± 1), a RH of 70% ± 10% °C and a photoperiod of 16L:8D, was measured at different nymphal densities (2, 5, 10, 15, and 20 per 15 cm²). [Results] The developmental duration was significantly shorter, (26.60 ± 0.57) d and (26.67 ± 0.45) d, respectively, at nymphal densities of 5 or 10 per 15 cm² (P < 0.05). Female fecundity was highest [(100.56 ± 1.25) progeny per female] at a nymphal density of 2, followed by a nymphal density of 5 [(61.29 ± 2.64) progeny per female]. The survival rate at a nymphal density of 5 was 75%, which was significantly higher than the other treatments (P < 0.05). The net reproductive rate (R0) was highest at a nymphal density of 2 (31.425), followed by that at a nymphal density of 5 (22.985). R0 decreased with increasing nymph density. The population doubling time (t) was shortest at a nymphal density of 5 (5.635 d), followed by a nymphal density of 10 (105.682 d). The t value was first negatively, then positively, correlated with nymphal density. [Conclusion] Nymphal density affects the population growth of P. solenopsis. A density of 5 nymphs / 15 cm² was the most suitable for the growth, development and reproduction of this species; lower or higher densities were less suitable. These findings are useful for further research on control methods for P. solenopsis. [ABSTRACT FROM AUTHOR]

Comprehensive Summary: The increasing demand for high‐energy storage systems has propelled the development of Li‐air batteries and Li‐O2/CO2 batteries to elucidate the mechanism and extend battery life. However, the high charge voltage of Li2CO3 accelerates the decomposition of traditional sulfone and ether electrolytes, thus adopting high‐voltage electrolytes in Li‐O2/CO2 batteries is vital to achieve a stable battery system. Herein, we adopt a commercial carbonate electrolyte to prove its excellent suitability in Li‐O2/CO2 batteries. The generated superoxide can be captured by CO2 to form less aggressive intermediates, stabilizing the carbonate electrolyte without reactive oxygen species induced decomposition. In addition, this electrolyte permits the Li metal plating/stripping with a significantly improved reversibility, enabling the possibility of using ultra‐thin Li anode. Benefiting from the good rechargeability of Li2CO3, less cathode passivation, and stabilized Li anode in carbonate electrolyte, the Li‐O2/CO2 battery demonstrates a long cycling lifetime of 167 cycles at 0.1 mA·cm–2 and 0.25 mAh·cm–2. This work paves a new avenue for optimizing carbonate‐based electrolytes for Li‐O2 and Li‐O2/CO2 batteries. [ABSTRACT FROM AUTHOR]
