Summary: The coating layer effectively reduces the negative effects at the interface between the active material and sulfide electrolyte in the cathode mixture. The influence of the coating layer at different voltage windows is investigated through the degradation mechanism of bare and LiNbO3 coated LiCoO2 electrodes in all-solid-state batteries. The interfacial stability and structural instability of LiCoO2 at different voltage windows significantly affect the electrochemical performance of the electrodes.

Summary: Garnet-type electrolytes with high ionic conductivity and wide electrochemical window have great potential in solid-state lithium batteries. However, the formation of Li2CO3 on the surface of garnet due to air exposure leads to uneven contact with Li-metal and undesirable dendrite growth. This study proposes a promising solution by replacing the Li2CO3 contaminant with a Li3PO4 layer formed through a molten salt treatment. The modified garnet exhibits a stable air-stable interface and low interfacial resistance, enabling high-performance solid-state lithium batteries.
