Researchers have developed a new quantum sensing approach to study battery performance at the nanoscale level. This method uses diamond nitrogen-vacancy (NV) centers to monitor individual electrode particles in real-time, providing insights into reaction mechanisms and failure modes. The NV sensors are highly sensitive to changes in temperature, stress, and magnetic fields, allowing for non-destructive monitoring of the electrochemical evolution within the battery. By observing these properties, the researchers were able to identify uneven phase transformations and magnetic behaviors within the electrode during charge and discharge cycles. This detailed understanding of the processes within battery materials offers a new way to analyze battery behavior and improve their lifespan and performance, ultimately leading to better batteries.
