Degradation of an argyrodite-type sulfide solid electrolyte by a trace of water: A spectroscopic analysis

Yusuke Morino et al.

Summary: Sulfide-based solid electrolytes are promising for solid-state lithium batteries due to their high ionic conductivities, suitable mechanical properties, and wide electrochemical windows. However, the hygroscopic nature of sulfide in these materials leads to the generation of toxic H2S gas upon reacting with water, which reduces the lithium-ion conductivity. On the other hand, it has been observed that conducting performance can be partially recovered through suitable heat treatment. This study employed multiple spectroscopic analyses to investigate the degradation and recovery mechanisms of a sulfide solid electrolyte under moisture exposure and vacuum heat treatment.

Degradation Analysis by X-ray Absorption Spectroscopy for LiNbO3 Coating of Sulfide-Based All-Solid-State Battery Cathode

Yusuke Morino et al.

Summary: The surface coating of cathode active material in all-solid-state batteries using sulfide-based solid electrolytes is a fundamental technology. LiNbO3 is one of the most representative materials used for this purpose. Analyzing the performance degradation of half cells exposed to harsh conditions, it was observed that the Nb element from the LiNbO3 coating remained at the interface, while the X-ray absorption spectroscopy (XAS) spectra indicated a decomposition reaction of the LiNbO3 coating, leading to oxidization deterioration of the sulfide electrolyte at the interface.

Impact of Surface Coating on the Low Temperature Performance of a Sulfide-Based All-Solid-State Battery Cathode

Yusuke Morino

Summary: Cathode coating is a crucial technology in sulfide-based all-solid-state batteries, providing protection and suppressing side reactions. In this study, it was found that coated sulfide-based all-solid-state batteries performed better in low-temperature environments compared to uncoated ones, demonstrating their applicability in such conditions.

AC Impedance Analysis of the Degeneration and Recovery of Argyrodite Sulfide-Based Solid Electrolytes under Dry-Room-Simulated Condition

Hikaru Sano et al.

Summary: This study investigates the degeneration mechanism of an argyrodite-type sulfide-based solid electrolyte under low-humid conditions. The results indicate that the electrolyte can degrade even under super-low humidity, and the grain surface degeneration leads to a decrease in lithium-ion conductivity at the grain boundary. The degenerated electrolyte surface can be partially recovered by heating, although some small-scale degeneration may occur during the heating process.

Deterioration process of argyrodite solid electrolytes during exposure to humidity-controlled air

Hirofumi Tsukasaki et al.

Summary: Sulfide-based solid electrolytes (SEs), with high ionic conductivity, are promising candidates for all-solid-state lithium-ion batteries. However, their conductivity decreases and toxic gas is generated when exposed to air. This study investigated the degradation process of argyrodite, a promising SE, primarily through transmission electron microscope observation, and found that the decrease in crystallinity and the generation of decomposed components contribute to the deterioration.

Degradation rate at the Solid-Solid interface of sulfide-based solid Electrolyte-Cathode active material

Yusuke Morino

Summary: This study analyzed the degradation rate of the cathode in all-solid-state lithium-ion batteries with sulfide-based solid electrolytes. The results showed that the degradation was controlled by two side reactions, and the cathode's performance was influenced by the decomposition of the solid electrolyte and the involvement of a coating material.

Electrochemical and material analyses for sulfide-based solid electrolyte-cathode interface under high voltage

Yusuke Morino et al.

Summary: The research highlights the importance of the active material coating of a cathode in all-solid-state lithium-ion batteries for charge transfer. The study also shows that cathodes with a LiNbO3 coating exhibit different charge transfer resistance trends after durability tests at various charging potentials. In addition, oxidation of sulfide at the solid electrolyte-coating interface was observed using time-of-flight secondary-ion mass spectrometry.
