Summary: In this study, electrically-conducting and semi-flowable zinc semi-solid electrodes were proposed for mechanically-rechargeable alkaline zinc-air batteries. High energy densities were achieved thanks to the compromised flowability of the electrodes. Zinc semi-flowable electrodes serve as a green energy carrier, which can be generated using renewable sources and easily stored, transported, and used.

Summary: Researchers propose a combination of hydrothermal and thermal treatment strategy to design a MnO-CNT@C3N4 composite cathode material. The optimized MnO-CNT@C3N4 exhibits excellent rate performance and high capacity due to the enhanced conductivity by CNTs and the alleviation of Mn2+ dissolution by C3N4. This work provides a viable strategy for the design of advanced cathodes for high-performance zinc ion batteries.

Summary: By experiment and density functional theory (DFT), it is confirmed that the reported direct nucleophilic attack of the carbanion onto coordinated dinitrogen does not exist. Instead, phenylithium reacts with one of the CO ligands to form an anionic acylcarbonyl dinitrogen metallate that decomposes to give a phenylate complex. The DFT calculations support the experimental results, and the direct attack of a nucleophile on metal-coordinated dinitrogen remains to be demonstrated.

Summary: Aqueous rechargeable batteries based on MnO2 are attracting attention due to their high theoretical capacity and redox potential, as well as their low cost and safety. However, the chemistry of MnO2 deposition/dissolution is not well understood, hampering its practical use in batteries. This study used an electrochemical quartz crystal microbalance technique to investigate the deposition/dissolution process and discovered that it involves pH-dependent Mn(iii)-intermediates. The presence of dissolved Mn3+ decreases the battery's performance, but the problem can be addressed by introducing redox mediators into the electrolyte.

Summary: Ultrafast femtosecond laser drilling was used to fabricate high-quality porous Al foils with precisely controlled hole size and porosity. The optimized laser-drilled Al foil with a hole diameter of 60 μm and a porosity of 15% showed high capacities at various charge/discharge rates. The improved performance was attributed to the large roughness and high surface area of the 3D Al foil, strong connection between electrode materials and porous current collector, high loading density and efficient utilization of active materials, good wettability and penetration of electrolyte, high Li+ diffusivity, and buffering of volume/stress variation in the 3D porous electrode.

Summary: In this study, the effects of multi-layer electrodes on VRFB electrode performance were investigated using a pore network modeling framework. The results showed that placing a highly permeable layer near the membrane increased the limiting current density by 57%. However, the desired structures should be selected based on a trade-off between current/power density and pressure drop.

Summary: LiNi0.5Mn1.5O4 (LNMO) with a spinel structure is a promising choice for Li-ion batteries, but its high operating voltages cause issues. By using a sodium alginate (SA)-xylan biopolymer as a binder, the SX28-LNMO electrode shows excellent performance with high capacity retention and rate capability. The SX28 binder forms a uniform CEI layer on the LNMO surface, preventing the oxidative decomposition of electrolytes and improving the battery's stability.
