Dr. Li XU has cooperated withresearchers from Griffith University and Queensland University of Technology. And, they had long-term collaboration on study of energy storage related research. Recently, they made progress on high performance sodium ion batteries. the works entitled “Low cost and green preparation process for a-Fe2O3 @ gum arabic electrode for high performance sodium ion batteries” was published in Journal of Materials Chemistry A (IF=8.262). This work was financially supported by the National Natural Science Foundation of China and Chinese Postdoctoral Foundation.
