Summary: A novel bifunctional cathode catalyst NiCeOx was proposed for high-performance lithium-oxygen batteries (LOBs). The combined action of NiO and CeO2 components was found to facilitate the decomposition of byproducts, increase the oxygen vacancy content in CeO2, and enhance the adsorption of oxygen and superoxide. The hollow and porous nanorod structure of NiCeOx provided abundant catalytic active sites and facilitated reactant transport and discharge product deposition, resulting in high specific discharge capacity and long lifespan.

Summary: In this study, benzo-crown ethers (BCEs) with varying cavity sizes are used as electrolyte additives to promote the growth of Li2O2 in Li-O-2 batteries. The cell with benzo-18-crown-6 ether (B18C6) exhibits the highest discharge capacity of 14948 mAh g(-1). These additives accelerate Li2O2 oxidation, improve reversibility, reduce charge overpotential, and prolong cycle life. Additionally, they also stabilize the Li anode by regulating Li+ migration and electron exchange, reducing dendritic growth and anode corrosion. This work provides insights into designing BCEs as additives for high-performance LOBs.

Summary: The morphology of Li2O2 discharge products in lithium-air batteries is determined by a seed layer formed by the combination of a cathode and an electrolyte, leading to improved reversibility and cyclability. The formation of a favorable interface between the carbon electrode and electrolyte also enhances oxygen evolution reaction, minimizing electrolyte decomposition.

Summary: In this study, the researchers constructed a metal-organic framework, UIO-66-NH2, containing Lewis base sites, and comprehensively investigated the pivotal mechanism of Lewis base sites in promoting the electrocatalytic reaction processes of lithium-oxygen batteries (LOBs). The density functional theory (DFT) calculations showed that the Lewis base sites acted as electron donors and enhanced the activation of O-2/Li2O2 during the discharged-charged process, leading to accelerated reaction kinetics of LOBs. Moreover, in situ Fourier transform infrared spectra and DFT calculations demonstrated that the Lewis base sites converted the Li2O2 growth mechanism from surface-adsorption growth to solvation-mediated growth by capturing Li+, thus weakening the adsorption energy of UIO-66-NH2 towards LiO2. The LOB based on UIO-66-NH2 showed high discharge specific capacity, low discharged-charged overpotential, and long cycling life.

Summary: This study systematically investigates the self-catalytic effect of in-situ electrochemical cobalt doping of Li2O2 and reveals its potential mechanism for enhancing the performance of lithium-oxygen batteries. Theoretical calculations show that Co impurities in the discharge products serve as active sites to promote the formation of Li3O4, switching the nucleation mechanism. Through a comprehensive investigation of the properties of Co-doped Li2O2 and Li3O4 compounds, it is found that Li3O4 exhibits better charge/mass transport and lower overpotential, leading to improved battery performance.

Summary: There is an increasing interest in developing robust and efficient sequential methods for reservoir simulation. The sequential fully implicit Newton (SFIN) method addresses the slow sequential coupling convergence issue when flow and transport problems are strongly coupled. However, the original SFIN algorithm requires fixed primary variables during the simulation. In this work, strategies are proposed to handle inconsistent primary variables and extend the SFIN method to the natural black-oil formulation.
