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: We studied the electrocatalytic processes in Mg-CO2 batteries using DFT calculations and RuO2 as a cathode catalyst. Adsorption of Mg and interaction with CO2 were found to be the initiation steps, but the formation of carbonate and oxalate intermediates at the catalytic site was thermodynamically unfavorable. MgC2O4 was predicted as the discharge product, but it is thermodynamically unstable and expected to decompose into MgCO3, MgO, and C.

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.
