A battery technology that opens the door to better-performing electric cars and wearable technologies received the University of Maryland’s 2021 Invention of the Year Award.
The winning invention, “Reversible Chemistry in Graphite Cathode for Safe, High Energy Batteries,” was developed by Chunsheng Wang, R.F. and F.R. Wright Distinguished Chair in the Departments of Chemistry & Biochemistry and Chemical & Biomolecular Engineering, and Chongyin Yang, former assistant research scientist in the Department of Chemical & Biomolecular Engineering. This technology has both high-energy density and efficiency and a fully aqueous design that—because it contains a “water-in-salt” electrolyte—is much safer, even as it outperforms most non-aqueous lithium batteries on the market.
The Invention of the Year award winner was announced April 21, 2021 at the Innovate Maryland event, which was part of UMD President Darryll Pines’ Inauguration Week activities.
Two other projects led by researchers in the College of Computer, Mathematical, and Natural Sciences were honored as Invention of the Year award finalists:
- “Scalable and Efficient Method of Creating Versatile Carbon Nanotubes” invented by Department of Chemistry and Biochemistry Professor YuHuang Wang, former visiting graduate student Hongbin Luo, and Peng Wang (Ph.D. ’19, chemistry)
- “Using Artificial Intelligence to Recognize Emotion” invented by Dinesh Manocha, Distinguished University Professor and Paul Chrisman Iribe Professor in the Departments of Computer Science and Electrical & Computer Engineering; Aniket Bera, assistant research professor in the University of Maryland Institute for Advanced Computer Studies; and computer science Ph.D. students Uttaran Bhattacharya, Rohan Chandra and Trisha Mittal
