説明:

For realizing oxide-based all-solid-state lithium-ion batteries, lowering sintering temperature of LiCoO2 cathode during battery fabrication is important subject to prevent undesired chemical reaction with other constituent substances. Here we report that the addition of LiOH aqueous solution to the LiCoO2 powder upon sintering improves the battery performance. Comparative study for the samples with and without LiOH solution, and with pure water by in situ transmission electron microscopy reveals that the liquid phase appears at much lower temperatures for the sample with the LiOH addition that improves the connectivity of LiCoO2 particles.
