Illumion, a University of Cambridge spinout developing advanced battery imaging technology, has raised £1.7 million in funding.

Illumion is commercialising charge photometry, a novel battery imaging technology that acts like a window into working batteries. Its first product, illumionONE, allows researchers to observe how individual battery particles behave during charge and discharge, providing insights that are difficult to capture with conventional testing methods. 

The company is also developing illumionX, a next-generation platform designed to help industrial battery teams translate those insights into faster development cycles and better quality-control decisions.
