Battery work published in Nature Communications

A paper by our group and collaborators at University of Wisconsin, Madison and MIT is recently published in Nature Communications. Dr. Liang Hong is a lead author and Fan is a co-author of the paper.

“Two-dimensional lithium diffusion behavior and probable hybrid phase transformation kinetics in olivine lithium iron phosphate”, https://www.nature.com/articles/s41467-017-01315-8

In this work, Dr. Linsen Li from Dr. Song Jin’s group at Wisconsin performed operando X-ray microscopy experiments on a common battery compound LiFePO4. We interpreted the experimental results with theoretical analysis and made a couple of notable findings, that is, 1) defects can fundamentally change Li diffusion behavior in this compound and may potentially benefit battery performance, and 2) there exists a hybrid phase transformation mechanism that is unique to intercalation compounds.
