Battery technology

Raman spectroscopy is an ideal tool for characterising lithium-ion batteries, both for research and development. Renishaw's inVia confocal Raman microscope is perfect for studies ranging from fundamental work on the materials involved, through to final product quality control and failure analysis.

Identification of materials

inVia can analyse all the key material types: organic and inorganic; crystalline and amorphous; solids, liquids, and gases.

Its high sensitivity makes identifying all the key battery components easy

  • carbon materials
  • metal oxides
  • polymers
  • electrolytes

Determination of distribution and structure

Raman mapping and imaging enables the study of the distribution of materials on electrode surfaces, or across cross-sections. The resulting data can be quantified, giving metrics such as fraction estimates and particle statistics.

  • Detecting low concentrations of binder. Detecting low concentrations of binder.

In situ measurements

Use inVia with a wide range of sample chambers, electrochemical cells and inert gas glove boxes. Raman data acquisition on inVia can also be triggered from devices such as potentiostats, enabling in situ and operando measurements.

Getting data, without damage

Lithium-ion battery components can be altered or damaged by high laser power densities. With Renishaw's line-focus laser illumination technology, power densities are reduced but total laser power is retained, so you can collect high quality data rapidly, and with confidence.


inVia's high sensitivity and high spatial resolution enable you to detect materials even if they are present in low concentrations, such as binders.

Correlated information

Combine inVia with an atomic force microscope and get not only chemical information from Raman spectroscopy, but also correlated surface topography information from AFM.
