Patent number: 9525190Abstract: Various embodiments of the invention disclose that the uptake of LiOiPr in Mg2(dobdc) (dobdc4?=1,4-dioxido-2,5-benzenedicarboxylate) followed by soaking in a typical electrolyte solution leads to a new solid lithium electrolyte Mg2(dobdc).0.35LiOiPr.0.25LiBF4.EC.DEC. Two-point ac impedance data show a pressed pellet of this material to have a conductivity of 3.1×10?4 S/cm at 300 K. In addition, the results from variable-temperature measurements reveal an activation energy of approximately 0.15 eV, while single-particle data suggest that intraparticle transport dominates conduction.Type: GrantFiled: March 28, 2016Date of Patent: December 20, 2016Assignee: The Regents of The University of CaliforniaInventors: Brian M. Wiers, Nitash P. Balsara, Jeffrey R. Long
