Measuring purity of lithium-ion battery electrolytes with Lovibond ICx

17 Jun 2026

This application note describes the use of the Lovibond® ICx spectrophotometer for precise color measurement of lithium-ion battery electrolytes, enabling robust quality control in battery manufacturing. Color is used as a critical indicator of purity, as even slight discoloration can signal contamination or degradation that may impact battery performance, safety and longevity.

Discover how the ICx instrument provides rapid, repeatable measurements using established color standards, including the Platinum-Cobalt (Pt-Co/APHA) scale, Yellowness Index and CIELAB color space. These methods enable accurate quantification of color changes, helping manufacturers maintain stringent electrolyte specifications required in high-performance battery production.

UV-Visible SpectroscopyUltraviolet-visible (UV-Vis) spectrophotometers are used to measure the interaction of UV and visible light with a sample, including transmission, reflectance & absorbance. The two major instrument classes are single-beam or double-beam spectrophotometers. More specialized equipment includes colorimeters, spectroradiometers and refractometers. Portable and microvolume spectrophotometers are also available. For the modular spectroscopy lab, explore a range of light sources for combination with a spectrograph/spectrometer and optics.
