On the Formation of Nanograined LiCo₂O₃(OH) Spinel-Type Material Synthesized via Modified Low-Temperature Sol-Gel Approach

Abstract:

A new lithium cobalt oxyhydroxide compound has been successfully synthesized. This new compound has been found to be related to the low temperature LiCoO₂(LT-LiCoO₂) spinel structure formed at low processing temperatures. With the use of a modified sol-gel approach, this compound with the composition of LiCo₂O₃(OH) can be successfully synthesized at around 150 °C. Structural analyses using powder X-ray diffraction (XRD) and selected area electron diffraction (SAED) suggest a cubic-spinel structure, which is also supported by FT-IR and TG/DTA analyses. In addition, from the TEM morphological analysis, a very fine nanograined LiCo₂O₃(OH) powder with an average grain size of 5 nm has been obtained. From these results, the presence of OH or water at low processing temperatures promotes a favorable formation of this structure. At higher temperatures (>400 °C), the phase transforms to a layered high-temperature LiCoO₂(HT-LiCoO₂) structure with the excess cobalt precipitated as Co₃O₄as suggested by the in-situ high temperature XRD analysis.
