Mapping Battery Materials with Atomic Precision

Scientific Achievement

An international team led by Foundry researchers showed how the ratio of materials that make up a lithium-ion battery electrode affects its structure at the atomic level, and how the surface is very different from the rest of the material.

Significance and Impact

This study is the first to reveal that a cathode’s surface has a different structure than the interior. Knowing how the internal and surface structure of a battery material changes over a wide range of compositions will aid future studies on cathode transformations and could also lead to new battery materials.
