INDIANAPOLIS — Cell phones could be thinner and electric cars could go farther with technology and materials developed by Jian Xie, associate professor in the Department of Mechanical Engineering at Indiana University-Purdue University Indianapolis, in conjunction with Argonne National Laboratory.
Nature Communications, an open-access journal that publishes high-quality research from all areas of the natural sciences, is publishing Xie’s paper, “Graphene-modified nanostructured vanadium pentoxide hybrids with extraordinary electrochemical performance for Li-ion batteries.”
Xie — a faculty member in the Purdue School of Engineering and Technology at IUPUI and a member of the campus’s Integrated Nanosystems Development Institute — and his research team have developed graphene materials and technology that will have a significant impact on electronics and electric vehicles. According to the paper, this technology shows great promise in helping redefine the size and efficiency of a wide array of products, particularly batteries.
These nano-structured materials have applications in energy storage (batteries and super capacitors) and energy conversion (fuel cells), among others. Possible examples include cell phones one-third the thickness of current cell phones and electric vehicles with driving ranges three times farther than current models.
“Technology breakthroughs in today’s world rely on our deep understanding of the fundamentals of materials, particularly on a nano-scale,” Xie said. “This collaborative work is a great example of how we can benefit from understanding the properties and structure of graphenes and metal oxides as well as their fundamental issues — single sheet graphene, electronic/ionic conductivity, structural stability, etc. — in order to solve engineering problems and develop applications. I am thrilled that this new approach will benefit the scientific community.”
Xie’s startup company, CE Helios, will commercialize this advanced technology. His approach will be used to develop next-generation battery technology that will have three times the current battery capacity — from 145 mAh/g of LiFePO4 to 438 mAh/g of V2O5.
“In order to understand the extraordinary performance of the novel materials, the researchers carried out in situ high-energy X-ray diffraction and in operando X-ray absorption spectroscopy measurements at the X-ray Science Division’s beamlines 11-ID-C and 20-BM-B, respectively,” said Advanced Photon Source/Argonne National Laboratory physicist Yang Ren.
“Such a combined application of two powerful and complementary hard X-ray techniques at the U.S. Department of Energy’s Advanced Photon Source not only elucidated the fundamental knowledge of the underlying mechanism at the atomic and electronic levels but also provided guidelines for future development of this new class of energy materials,” he said.
Papers published by Nature Communications, a journal of the Nature Group, represent important advances of significance to specialists within each field. The journal has an Impact Factor of 10.742, according to the 2013 Journal Citation Reports Science Edition.
