Researchers have found that the irregular movement of lithium ions in next-generation battery materials could be reducing their capacity and hindering their performance.

The team, led by the University of Cambridge, tracked the movement of lithium ions inside a promising new battery material in real time.
It had been assumed that the mechanism by which lithium ions are stored in battery materials is uniform across the individual active particles. However, the Cambridge-led team found that during the charge-discharge cycle, lithium storage is anything but uniform.
When the battery is near the end of …
