Summary: We report a strategy for the synthesis of chiral mesoporous silica nanospheres with molecular-scale-like chirality. The functionalization of micelles with chiral amide gels leads to the growth of molecularly chiral silica sols, which self-assemble into dendritic large mesoporous silica nanospheres with molecular chirality. The resulting chiral mesoporous silica shows abundant large mesopores, high pore volumes, high surface areas, and exhibits notable optical activity. It also displays good chiral stability and exhibits significant inhibition of β-amyloid protein aggregation formation and cytotoxicity.

Summary: Zn-gas batteries have been highly regarded in energy conversion and storage due to their high theoretical energy density. Besides the widely studied Zn-air/oxygen battery, other novel Zn-gas batteries, such as Zn-CO2, Zn-N2, and Zn-NO batteries, have emerged as a dual-purpose strategy to provide energy power and simultaneously upgrade pollutant/useless gases. This technology offers a low-cost and controllable method to produce value-added chemicals and fuels at the cathode driven by surplus electricity. However, there is a need for guidance in catalyst selection and energy system construction. This review summarizes recent achievements in typical Zn-gas batteries beyond Zn-air/oxygen, including their energy storage mechanism, production of value-added chemicals, and design of cathodic catalyst materials. The challenges and possible future directions of Zn-gas batteries are also discussed.

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: Aqueous metallic zinc batteries have gained attention as an alternative to lithium-ion batteries due to their safety and eco-friendly characteristics. However, parasitic reactions during zinc plating/stripping have hindered their stability and reversibility. In this study, a strategy involving betaine zwitterions was proposed to improve the electrode-electrolyte interface, leading to improved zinc plating/stripping kinetics and increased coulombic efficiency. The strategy was found to effectively stabilize the zinc anode and enable long-term cycling with high capacity retention in Zn||Cu and Zn||MnO2 half- and full-cell configurations.

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: Achieving high reversibility between the electrodes and electrolyte is crucial for the durability of secondary batteries. Rechargeable zinc-air batteries (RZABs) undergo irreversible changes in the zinc anodes and air cathodes during cycling. Through experiments and calculations, it was found that nanosized mossy zinc dominates the later cycling stage due to increased zincate concentration caused by hydrogen evolution. This mossy structure catalyzes the hydrogen evolution, resulting in oxide passivation on electrodes, low true Coulombic efficiencies, and short battery life. Inspired by these findings, a novel overcharge-cycling protocol is presented to compensate for the Coulombic efficiency loss and extend battery life significantly.
