The University of Cambridge team discovered the method using a low-cost imaging technique. Researchers from the University of Cambridge have developed a simple and low-cost lab-based technique that makes it possible for them to view the lithium ions moving in smartphone batteries in real time. This allowed the researchers see the movement within the lithium-ion batteries as they were charging. As a result, they could see how the lithium ions moved as the smartphone batteries were charging as well as how they were discharging. This was a first for researchers.…
