In general, Raman allows the in situ characterization of microbatteries through an observation window. This will enable correlations between battery performance and molecular/crystallinity changes. In addition, the capabilities of current Raman microscopes,

which include

fast mapping and high throughput to follow the rapid ion diffusion and migration.

high spatial resolution to discriminate down to ~1µm volumes in the transparent electrolyte.

will make characterization of microbatteries quite feasible with a Raman microscope.
