Abstract:
Synthesis of any material results not only in the fabrication of the desired composition, but also some amount of undesired second phases. Here we demonstrate that structural heterogeneity in a negative electrode material Li4Ti5O12 with sub-micron grain size synthesized using standard solid-state method can be described locally via structural characterization of single particles using a combination of standard micro-Raman spectroscopy together with scanning electron microscopy. Proposed approach can be used as a kind of low-cost alternative to high-resolution transmission electron microscopy for local structural characterization and a supplement to integral X-ray diffraction techniques not only for Li4Ti5O12, but also for a wide range of commercial products.
