Illumion

Illumion is a University of Cambridge spinout commercialising charge photometry, a patented optical technique that reveals how individual battery particles behave in real time during charge and discharge. Its first instrument, illumionONE, serves battery researchers in academia and industry, and the company is developing illumionX, a next-generation platform for industrial battery development and quality control. The technology grew out of Faraday Institution-supported research, and Illumion collaborates with battery R&D teams and manufacturers across the battery value chain.
