Diagnosis lithium ion battery using Bragg coherent diffractive imaging

  • News

By using Bragg coherent diffractive imaging, our collaborators and us developted the operando characterization of the topological defects in the cathode nanoparticles of lithium ion battery. Based on this technique,  three-dimensional imaging of dislocation dynamics in individual battery cathode nanoparticles  is realized while the battery working at high voltage. It opens a pathway for facilitating improvement and rational design of nanostructured materials for energy storage and conversion devices. This work is pubilished on Science and reported by Jacobs School of Engineering, UCSD.
