US Patent:

20140045074, Feb 13, 2014

Filed:

Aug 8, 2013

Appl. No.:

13/962718

Inventors:

Brian M. Wiers - Berkeley CA, US
Nitash P. Balsara - El Cerrito CA, US
Jeffrey R. Long - Oakland CA, US

Assignee:

The Regents of the University of California - Oakland CA

International Classification:

H01M 10/056
H01M 10/0525

US Classification:

429306

Abstract:

Various embodiments of the invention disclose that the uptake of LiOPr in Mg(dobdc) (dobdc=1,4-dioxido-2,5-benzenedicarboxylate) followed by soaking in a typical electrolyte solution leads to a new solid lithium electrolyte Mg(dobdc).0.35LiOPr.0.25LiBF.EC.DEC. Two-point ac impedance data show a pressed pellet of this material to have a conductivity of 3.1×10S/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.

Abstract:

The electrochemical carbon dioxide reduction reaction (CORR) provides opportunities to synthesize value-added products from this greenhouse gas in a sustainable manner. Efficient catalysts for this reaction are provided that selectively drive COreduction over the thermodynamic and kinetically competitive hydrogen evolution reaction (HER) in organic or aqueous electrolytes. The catalysts are metal-polypyridyl coordination complexes of a redox non-innocent terpyridine-based pentapyridine ligand and a first-row transition metal. The metal-ligand cooperativity in [Fe(tpyPY2Me)] drives the electrochemical reduction of COto CO at low overpotentials with high selectivity for CORR (>90%).
