AI Article Synopsis
- The study focuses on the issue of degradation in the amorphous-LiNbO coating of sulfide-based all-solid-state batteries (SBs) during high-voltage charging, which negatively impacts battery performance.
- Researchers found that oxygen (O) is generated from the Li extraction in the coating layer, resulting in an oxidative solid electrolyte that further deteriorates battery efficiency.
- By substituting elements in the coating (specifically using amorphous-LiNbP O), oxygen release is minimized, leading to more stable charge-discharge reactions and improved energy density in SBs.
Article Abstract
The cathode surface of sulfide-based all-solid-state batteries (SBs) is commonly coated with amorphous-LiNbO in order to stabilize charge-discharge reactions. However, high-voltage charging diminishes the advantages, which is caused by problems with the amorphous-LiNbO coating layer. This study has investigated the degradation of amorphous-LiNbO coating layer directly during the high-voltage charging of SBs. O generation via Li extraction from the amorphous-LiNbO coating layer is observed using electrochemical gas analysis and electrochemical X-ray photoelectron spectroscopy. This O leads to the formation of an oxidative solid electrolyte (SE) around the coating layer and degrades the battery performance. On the other hand, elemental substitution (i.e., amorphous-LiNbP O) reduces O release, leading to stable high-voltage charge-discharge reactions of SBs. The results have emphasized that the suppression of O generation is a key factor in improving the energy density of SBs.

Photocatalytic overall water splitting is a promising approach for a sustainable hydrogen provision using solar energy. For sufficient solar energy utilization, this reaction ought to be operated based on visible-light-active semiconductors, which is very challenging. In this work, an F-expedited nitridation strategy is applied to modify the wide-bandgap semiconductor SrTiO for visible-light-driven photocatalytic overall water splitting.

Influenza A viruses (IAVs) must navigate through a dense extracellular mucus to infect airway epithelial cells. The mucous layer, composed of glycosylated biopolymers (mucins), presents sialic acid that binds to ligands on the viral envelope and can be irreversibly cleaved by viral enzymes. It was recently discovered that filamentous IAVs exhibit directed persistent motion along their long axis on sialic acid-coated surfaces.

During fast-charging, uneven lithium plating on the surface of commercial graphite anode impedes the electrochemical performance of lithium-ion batteries, causing a safety issue. The formation of a passivation layer, the solid-electrolyte interphase (SEI), due to side reactions with the organic electrolyte, correlates with long-term cycling performance under fast-charging conditions, necessitating comprehensive analysis. Herein, it is demonstrated that a molybdenum disulfide (MoS) coating on natural graphite (NG) modulates the properties of the SEI layer, enabling reduction of the charging time and the enhancement of long-term cycling performance.
