SOLID ELECTROLYTES FOR next GENERATION . BATTERIES . PI: John B. Goodenough Presented by: Long Wang Texas Materials Institute The University of Texas at Austin Project ID: ES15. DOE Vehicle Technologies Annual Merit Review Meeting May 14-18, 2012. This presentation does not contain any proprietary or confidential information. 1 The University of Texas at Austin Overview Timeline Barriers Project Start Date-Sept. 2010 Stable SOLID electrolyte with Project End Date- Aug. 2013 Li > 10-4 S/cm Percent complete: 50% complete Thin SOLID electrolyte membrane with enough mechanical strength Budget Partners Funding received in FY10-FY11.

Existing Solid Electrolytes . 7 . Garnet structure electrolytes are electrochemically stable with a larger window than commercial LISICON® membrane and are not sensitive to water as sulfides, so they are a promising separators for flow-through batteries using aqueous solutions. Contamination by aluminum at high temperature makes it
