Us Patents

Nonaqueous Electrolyte Compositions Comprising Silyl Oxalates

US Patent:
2019024, Aug 8, 2019
Filed:
Jul 27, 2017
Appl. No.:
16/326466
Inventors:
- Brussels, BE
Stephen E. BURKHARDT - Wilmington DE, US
Kostantinos KOURTAKIS - Media PA, US
Brian LEVY-POLIS - Newark DE, US
International Classification:
H01M 10/0567
H01M 10/0568
H01M 10/0569
C07F 7/18
Abstract:
Disclosed herein are electrolyte compositions comprising a fluorinated solvent, at least one silyl oxalate represented by the formulas RR′Si(CO), wherein R and R′ are each the same or different from each other and independently selected from C-Calkyl, C-Calkenyl, C-Calkynyl, or C-Caryl radical, optionally comprising at least one substituent selected from halogen, hydroxyl, alkoxy, carbonyl, and carboxyl groups; and LiPF6. Also disclosed herein are electrolyte compositions comprising a fluorinated solvent and a lithium oxalato phosphate salt represented by the formula LiPF(CO), wherein q is 1, 2 or 3; wherein the oxalato phosphate salt comprises at least a portion that is derived from at least one silyl oxalate as defined herein. The electrolyte compositions are useful in electrochemical cells, such as lithium ion batteries.

Nonaqueous Electrolyte Compositions Comprising Lithium Oxalato Phosphates

Stephen E. BURKHARDT - Wilmington DE, US
Kostantinos KOURTAKIS - Media PA, US
Brian LEVY-POLIS - Newark DE, US
Jun J. LIU - Wilmington DE, US
Mark Gerrit ROELOFS - Earleville MD, US
International Classification:
H01M 10/0568
H01M 10/0569
H01M 10/0567
H01M 4/131
Abstract:
Described herein are: An electrolyte composition comprising a) a fluorinated solvent for an electrolyte salt; b) an oxalate salt represented by the Formula LiPF(Ox), wherein Ox is an oxalate moiety and q is 1, 2 or 3; and c) optionally, at least one electrolyte salt. In some embodiments, the electrolyte composition comprises a mole ratio of Ox/P in the range of from 0.001 to 5. The electrolyte compositions are useful in electrochemical cells, such as lithium ion batteries.
