Physics researchers at Virginia Commonwealth1 University have discovered that most of the electrolytes used in lithium-ion batteries -- commonly found in consumer electronic devices -- are superhalogens, and that the vast majority of these electrolytes contain toxic2 halogens. At the same time, the researchers also found that the electrolytes in lithium-ion batteries could be replaced with halogen-free electrolytes that are both nontoxic and environmentally friendly.The significance [of our findings] is that one can have a safer battery without compromising its performance, said lead author Puru Jena, Ph.D., distinguished3 professor in the Department of Physics of the College of Humanities and Sciences. The implication of our research is that similar strategies can also be used to design cathode materials in Li-ion batteries.The article, Superhalogens as Building Blocks of Halogen-free Electrolytes in Li-ion Batteries, by Jena, postdoctoral researcher Santanab Giri, Ph.D., and then-graduate student Swayamprabha Behera, Ph.D., will appear in a forthcoming issue of the chemistry journal Angewandte Chemie International Edition, which has posted the study online.Jena said he hopes that the articles findings will lead to production of safer, less toxic batteries.We hope that our theoretical prediction will stimulate4 experimentalists to synthesize halogen-free salts which will then lead manufacturers to use such salts in commercial applications, he said.
