Summary: Aqueous zinc-based batteries are expected to be low-cost and high energy density, however, dendrite formation during charging remains a major issue. In situ TEM observations revealed that dendrite growth from the zinc anode causes short-circuiting and cycle degradation in zinc-based batteries. Characterization of electrochemical zinc deposition is crucial for realizing long life rechargeable zinc-based batteries.

Summary: Rechargeable zinc-air batteries are considered highly promising for energy storage due to their theoretical energy density, safety, and environmental friendliness. However, the uncontrolled growth of zinc dendrites hinders their stability and performance. This study presents a 3D printed electrode with chemical etching and electro-deposition of zinc, which exhibits excellent reversibility and dendrite-free growth. The 3D electrode shows improved stability and coulombic efficiency, cycling continuously for 1050 hours at 10 mA cm-2. The electrode's impedance is also lower compared to a 2D electrode, indicating better interface compatibility for zinc deposition. The corrosion-resistant electrode prepared through this method achieves a cycle life of over 1000 hours.

Summary: In this research, it was found that Na+ cations can inhibit dendrite growth during Zn plating, while F- anions can effectively inhibit the formation of Zn-4(OH)(6)SO4·nH2O during Zn stripping. NaF exhibits a stronger ability to suppress Zn dendrite formation compared to Na2SO4 during stripping/plating processes. The systematic Zn//Zn cell with 0.1 M NaF additive shows a stable cycling performance of 368 h, significantly longer than Na2SO4 (253 h) and blank sample (171 h). This work provides a novel strategy for alleviating dendrite growth by optimizing the anion of additives. The excellent electrochemical performances of various Zn-based energy storage devices verify the broad commercial prospects of aqueous electrolytes with NaF additive.

Summary: Primary quasi-solid Al-air batteries using hydrogels have gained attention due to their high energy density, good handling, safety, and reliability. However, developing hydrogel electrolytes with high ionic conductivity and water retention remains challenging. This study introduces a modified hydrogel electrolyte using kappa-carrageenan (KC) in poly(acrylic acid) (PAA) for solid-state Al-air batteries. The results show that these hydrogels demonstrate outstanding water retention and high ionic conductivity, attributed to the amorphous phase and hydrophilic group of KC. Additionally, adding KC extends the lifespan of the solid-state Al-air battery at a current density of 5 mA cm-2.

Summary: Scientists have developed a selective epoxidation strategy using a heterogeneous catalyst comprising iridium single atoms, resulting in molecular-like catalysis. This strategy provides near-perfect selectivity (99%) for producing valuable ethylene oxide through pi-coordination between the iridium metal center and ethylene or molecular oxygen. The formation of five-membered oxametallacycle intermediates facilitates the high selectivity for ethylene oxide. This molecular catalysis model of single-atom catalysts can effectively inhibit the overoxidation of the desired product.

Summary: In this study, a efficient strategy for stabilizing copper with silica was proposed, resulting in the synthesis of reconstruction-resistant CuSiOx amorphous nanotube catalysts with abundant atomic Cu-O-Si interfacial sites. The strong interfacial interaction between copper and silica ensured the ultrastability of the Cu-O-Si interfacial sites during the CO2 reduction reaction, exhibiting high CO2-to-CH4 selectivity (72.5%) and stability (FECH4 remains above 60% after 12 hours of testing). A remarkable CO2-to-CH4 conversion rate of 0.22 mu mol cm-2 s-1 was also achieved in a flow cell device. This work provides a very promising route for the design of highly active and stable copper-based CO2 reduction catalysts.

Summary: Through regulating the synthesis process, ZnCo2O4 with a unique Co site was obtained by replacing Co2+ and Co3+ sites in Co3O4 with Zn and Al atoms. The Li-O-2 batteries based on ZnCo2O4 showed longer cycle life than that of CoAl2O4, suggesting that Co-Oh(3+) site is a relatively better geometric configuration than Co-Td(2+) site for Li-O-2 batteries.

Summary: In this study, a polyacrylic acid hydrogel integrating KF and KOH (F@PAA) was developed to decompose the parasitic product Al(OH)(3) and improve the discharge performance of wearable Al-air batteries. The competitive attack of F on Al-O cleared the ions channels on the anode surface, leading to improved battery durability. The introduction of 1.0 M F into the F@PAA hydrogel resulted in optimal byproduct decomposition and battery discharge. The proposed hydrogel enabled a wearable Al-air battery to achieve a maximum power density of 58.28 mW/cm(2), high capacity of 2199.10 mAh/g, and anode efficiency of 73.80% at 10 mA/cm(2). Additionally, the development of interface cleaning technology in wearable Al-air batteries improved the key performance of the battery by up to 104.08%.

Summary: With the rapid development in flexible and wearable electronic devices, there is a growing demand for soft power supplies with high energy density and long service life. Rechargeable zinc-air batteries have the potential to meet this demand with their high electrochemical energy and relative safety. However, the performance of the polymer electrolyte and interface compatibility with the electrodes are crucial factors affecting the battery's output performance and cycle stability. Moreover, the interference of carbon dioxide in the environment further weakens the battery's performance, making CO2-tolerance a key research direction for zinc-air batteries. This study reviews the working principle of zinc-air batteries and proposes a new prospect for the research and development of high-performance solid zinc-air batteries.
