Scientists Track 3D Nanoscale Changes in Rechargeable Battery Material During Operation

First 3D nanoscale observations of microstructural degradation during charge-discharge cycles could point to new ways to engineer battery electrode materials for better performance.

Scientists at the U.S. Department of Energy's Brookhaven National Laboratory have made the first 3D observations of how the structure of a lithium-ion battery anode evolves at the nanoscale in a real battery cell as it discharges and recharges. The details of this research, described in a paper published in Angewandte Chemie, could point to new ways to engineer battery materials to increase the capacity and lifetime of rechargeable batteries.
