Cocrystals of salts with “soft” organic molecules as a new class of solid electrolytes for safer batteries
An increase in demand for high-power and high-capacity lithium ion batteries has led to steadily increasing demand for these devices. The maximum power density of a battery is highly dependent upon the electrolyte separator between the battery electrodes, and for the highest power density batteries, the current norm is the use of organic liquid electrolytes. While these electrolytes give good device properties, they permit dendrite formation which can short the battery, leading to heat, fires, and explosions resulting from ignition of the flammable liquid electrolyte. Therefore a search for less flammable, solid alternatives is a major goal of the industry. While most efforts have centered around polymer and ceramic solid electrolytes, our work on the generation of cocrystaline molecular solid electrolytes will be presented. The selection of "soft" (charge diffuse, polarizable) molecules as matrix molecules for ion conduction results in conductivity properties generally superior to polymer electrolytes, and mechanical properties superior to brittle ceramic electrolytes. Several molecular-salt cocrystal systems will be presented, and their structures, thermal and mechanical properties, and conductivities will be discussed.
Professor Michael Zdilla is an inorganic chemist at the Department of Chemistry at Temple University in Philadelphia PA. A native of Lancaster County, PA, Prof. Zdilla attended Millersville University for his Bachelors in Science in biochemistry, and studied synthesis of biologically inspired molybdenum complexes for his thesis research. Zdilla attended graduate school and obtained his Ph.D in inorganic chemistry at Princeton University under the supervision of Sonny C. Lee, performing inorganic synthesis of iron-nitrogen cluster mimics of the nitrogenase iron-molybdenum cofactor. As a postdoctoral fellow, he studied catalysis and mechanistic bioinorganic chemistry on synthetic models of metalloporphyrin redox enzymes under the supervision of Mahdi M. Abu-Omar. Since starting his independent career at Temple he has published 33 papers on the topics of synthetic and mechanistic inorganic chemistry, catalysis, materials science, nanoscience, energy science, and crystallography. He has been the recipient of the NSF Career Award, the Office of Naval Research Young Investigator Award, the Camille Dreyfus Teacher Scholar award, and was named the inaugural Robert L. Smith Early Career Chair in Chemistry at Temple University.
