Abstract
Official abstract text for this publication.
Various embodiments of the invention disclose that the uptake of LiO i Pr in Mg 2 (dobdc) (dobdc 4− =1,4-dioxido-2,5-benzenedicarboxylate) followed by soaking in a typical electrolyte solution leads to a new solid lithium electrolyte Mg 2 (dobdc).0.35LiO i Pr.0.25LiBF 4 .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.
First claim
Opening claim text (preview).
We claim: 1. A solid lithium electrolyte comprising: a metal-organic framework comprising Mg 2 (dobdc), wherein dobdc=1,4-dioxido-2,5-benzenedicarboxylate; and a lithium alkoxide comprising lithium isopropoxide (LiO i Pr). 2. The solid lithium electrolyte of claim 1 , wherein metal-organic framework comprises open metal cation Mg 2+ sites. 3. The solid lithium electrolyte of claim 1 , wherein metal-organic framework further comprises lithium tetrafluoroborate (LiBF 4 ). 4. The solid lithium electrolyte of claim 1 , wherein metal-organic framework further comprises ethylene carbonate (EC). 5. The solid lithium electrolyte of claim 1 , wherein metal-organic framework further comprises diethyl carbonate (DEC). 6. The solid lithium electrolyte of claim 1 comprising Mg 2 (dobdc).0.35LiO i Pr.0.25LiBF 4 .EC.DEC.
