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 Li 4 Ti 5 O 12 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 Li 4 Ti 5 O 12 , but also for a wide range of commercial products.
