Summary: Rechargeable lithium-oxygen batteries have high potential as energy storage devices, but their performance is hindered by slow oxygen reduction and evolution reactions at the cathodes. Introducing light into the batteries can improve reaction kinetics, but the understanding of this process is limited. This tutorial review summarizes recent findings on photoinvolved Li-O-2 batteries and discusses the challenges and prospects, considering the interdisciplinary nature of the field.

Summary: In this study, the true reaction sites of Li2O2 in a Li-O-2 battery were discovered using a rotate ring-disk electrode, and it was determined that the reduction of O-2 to Li2O2 occurs simultaneously at both electrode interfaces. This new finding raises new challenges and strategies for catalyst design in Li-O-2 batteries.

Summary: Mono-solvent DMC electrolyte is used for the first time in contact prelithiation, and the low-organic-content REI formed by this electrolyte is found to be a mixed ion/electron conductor. As a result, electron channels can be maintained even when the Li source is completely wrapped by the DMC-derived REI, leading to outstanding Li source utilization and negligible dead Li yield.

Summary: Compared with polycrystal cathode materials, single-crystal cathode materials exhibit excellent structural stability and high voltage stability during cycling. However, the origin of this high voltage stability is not well understood. In this study, the evolution of phase transitions was tracked, revealing that single-crystal cathode materials effectively suppress destructive volume change and formation of H3 phase, thereby maintaining high voltage stability.

Summary: In this study, the gas evolution during the electrochemical oxidation of lithium carbonate on carbon substrates was quantified using an in-situ differential electrochemical mass spectrometry-gas chromatography coupling system. The results showed that lithium carbonate mainly decomposes to carbon dioxide and singlet oxygen via an electrochemical process. It was also found that cobalt(II,III) oxide can stabilize the precursor of singlet oxygen, thus inhibiting the formation of singlet oxygen and consequent side reactions.

Summary: The capacity losses in Li anodes are mainly caused by the formation of electronically isolated Li-0 and parasitic reactions that form the solid electrolyte interphase (SEI). The quantification of losses has primarily focused on Li-0, but at high Coulombic efficiency (CE), SEI losses become dominant and need to be minimized. By using quantitative titration, a variety of key SEI phases were tracked, revealing that a minor phase, Li2C2, exhibited a clear inverse correlation with CE, suggesting its significant role in SEI function.

Summary: Li-O-2 batteries are considered as the ultimate energy storage technology with the potential to store large amounts of electrical energy. Catalytic intervention, particularly involving cobalt-tetramino-benzoquinone (Co-TABQ) nanosheets, plays a crucial role in improving the reversibility and kinetics of cathode reactions. Orbital interactions of metal ions with ligands in Co-TABQ nanosheets are critical for light harvesting and oxygen electrocatalysis in Li-O-2 batteries.

Summary: This study used differential electrochemical mass spectrometry (DEMS) to investigate the influence of common impurity lithium carbonate on the formation and reaction mechanisms of oxygen species in lithium-excess layered oxide cathode materials. The presence of lithium carbonate on the cathode surface leads to the formation of organic fragments containing diatomic oxygen during charging, primarily originating from the NMC lattice rather than the lithium carbonate itself. The results suggest that the reactive oxygen released from the NMC lattice is triggered by the oxidation of surface lithium carbonate.

Summary: The practical use of lithium metal in high-energy density lithium metal batteries is hindered by the continuous formation of lithium dendrites and irreversibly formed solid electrolyte interfaces (SEIs). By combining operando nuclear magnetic resonance (NMR) spectroscopy with ex situ titration gas chromatography (TGC) and mass spectrometry titration (MST) techniques, a solid foundation for quantifying the evolution of dead lithium metal and SEI separately has been established. The existence of LiH has been identified, causing deviations in the quantification results of dead lithium metal obtained by these techniques. Quantitative studies on the formation of inactive lithium under different operating conditions have revealed a general two-stage failure process for lithium metal.

Summary: Anode-free batteries are promising for high-energy applications, but face challenges with cycling stability due to limited lithium sources. In this study, researchers preloaded Li2O onto the cathode of an initial-anode-free cell to provide additional lithium for offsetting irreversible lithium loss during long-term cycling. By utilizing O-2(-) species released through Li2O oxidation and a fluorinated ether additive, a LiF-based layer was constructed at the cathode/electrolyte interface to passivate the cathode surface and inhibit the detrimental oxidative decomposition of ether solvents. As a result, a long-life 2.46 Ah initial-anode-free pouch cell with a gravimetric energy density of 320 Wh kg(-1) was achieved, maintaining 80% capacity after 300 cycles.

Summary: This study deconvolutes the mixed redox processes in a Ni-based DRX material, revealing a much lower Ni oxidation efficiency than initially designed due to the competition of oxygen redox. The chemical approach presented in this work and its future extension can resolve and quantify various mixed redox processes in different DRX, allowing clear correlations among material design, deconvoluted redox capacities, and battery performance.
