Summary: In lithium-oxygen batteries, the impact of nanopore size on Li2O2 formation and decomposition reactions in porous carbon cathodes is not well understood. In this study, the effect of pore size in the range of 25-200 nm was investigated using a highly ordered porous cathode matrix. The results showed that at a nanopore size of 25 nm, a film-like Li2O2 with a thickness of 2-5 nm was formed, possibly via a surface-driven mechanism. As the nanochannel became larger, the Li2O2 film thickness saturated at around 10 nm, and crystalline Li(2)O(2) particles were formed by a solution-mediated mechanism.

Summary: This study demonstrates the potential of cesium lead bromide perovskite (CsPbBr3) nanocrystals as a high-performance cathode for Li-O-2 batteries, achieving the lowest charge overpotential and best cycling performance among reported perovskite-based Li-O-2 cells, setting a new benchmark. The density functional theory (DFT) calculations further support that the rate-limiting step in the oxygen evolution reaction (OER) process is the decomposition of LiO2, and the weak adsorption strength between CsPbBr3 surfaces and LiO2 contributes to the low charge overpotential in CsPbBr3-based Li-O-2 batteries.

Summary: The study demonstrates the production of rechargeable Na/Cl-2 and Li/Cl-2 batteries with a microporous carbon positive electrode, aluminium chloride in thionyl chloride as the electrolyte, and either sodium or lithium as the negative electrode. The reversible Cl-2/NaCl or Cl-2/LiCl redox in the microporous carbon allows for rechargeability at the positive electrode side, while the thin alkali-fluoride-doped alkali-chloride solid electrolyte interface stabilizes the negative electrode, both of which are critical for secondary alkali-metal/Cl-2 batteries.

Summary: Metal-metal batteries have great potential for large-scale energy storage systems due to their simple manufacturing process and low production costs. However, the migration of metal cations from the cathode to the anode reduces capacity and affects battery stability. To address this issue, a coating of poly (ionic liquid) (PIL) with poly(diallyldimethylammonium bis(trifluoromethanesulfonyl)imide) (PDADMA(+)TFSI(-)) on a commercial polypropylene (PP) separator is utilized as an anion exchange membrane for a copper-lithium battery. The PIL coating improves Coulombic efficiency, long-term cycling stability, and inhibits self-discharge of the battery.

Summary: Two sodium-rich transition metal oxides, Na2MoO4 and Na2WO4, with the same spinel structure, are studied as cathode materials for Na-ion batteries for the first time. Both compounds can be activated by anionic redox reaction during initial charge, providing reversible capacity between 1.2 and 4.7 V. Na2WO4 exhibits larger Na extraction/insertion and better cycle stability compared to Na2MoO4, likely due to its better structural integrity and stability against oxygen loss.

Summary: The main challenge for acidic water electrolysis is the lack of active and stable oxygen evolution catalysts based on abundant materials. This work presents a new design strategy for activating stable materials, deemed unsuitable due to their semiconducting nature. By adding both n-type and p-type dopants, the reactivity of the catalyst can be tuned to allow for oxygen adsorption and desorption under reaction conditions. Experimental verification on TiO2 suggests that co-substitution can be used to activate stable materials for acid water electrolysis catalysts.
