Charge Photometry
Seeing inside batteries with light
A new innovative technology for studying batteries
Charge photometry images the electrode during battery operation, capturing local changes to the state-of-charge and morphology of individual active particles, alongside synchronised electrochemistry data.
Compatible with Li-ion and beyond Li-ion chemistries, the general applicability and orthogonality of the technique unlocks new possibilities for battery research and development in the pursuit of next-generation battery materials.
