Halogenated organosilicon electrolytes, methods of using them, and electrochemical devices containing them

Described herein are liquid, organosilicon compounds that including a substituent that is a cyano (&#x2014;CN), cyanate (&#x2014;OCN), isocyanate (&#x2014;NCO), thiocyanate (&#x2014;SCN) or isothiocyanate (&#x2014;NCS). The organosilicon compounds are useful in electrolyte compositions and can be used in any electrochemical device where electrolytes are conventionally used.

The electrolyte includes one or more salts and a silane. The silane has a silicon linked to one or more first substituents that each include a poly(alkylene oxide) moiety or a cyclic carbonate moiety. The silane can be linked to four of the first substituents. Alternately, the silane can be linked to the one or more first substituents and one or more second substituents that each exclude both a poly(alkylene oxide) moiety and a cyclic carbonate moiety.

Electrolyte including silane for use in electrochemical devices

Disclosed are lithium/carbon monofluoride batteries suitable for long term use at highly elevated temperatures. Organosilicon electrolytes having low vapor pressure and high flash points are used, along with lithium salts and ceramic separators. Methods of using these batteries at high temperatures are also disclosed.

Lithium/carbon monofluoride batteries with organosilicon electrolytes

Disclosed are hydroxy terminated alkylsilane ethers with oligoethylene oxide substituents. They are suitable for use as electrolyte solvents and particularly well suited for use with aqueous environment electrolytic capacitors. Methods for synthesizing these compounds are also disclosed.

Organosilicon glycol-based electrolytes with a hydroxy terminus

One example of the disiloxanes include a backbone with a first silicon and a second silicon. The first silicon is linked to a first substituent selected from a group consisting of: a first side chain that includes a cyclic carbonate moiety; a first side chain that includes a poly(alkylene oxide) moiety; and a first cross link links the disiloxane to a second siloxane and that includes a poly(alkylene oxide) moiety. In some instance, the second silicon is linked to a second substituent selected from a group consisting of: a second side chain that includes a cyclic carbonate moiety, and a second side chain that includes a poly(alkylene oxide) moiety.

Electrochemical device having electrolyte including disiloxane

Disclosed are electrochemical double-layer capacitors having an electrode with a substrate and an electrolyte/quaternary ammonium salt capable of penetrating the substrate. Such salts have a moiety of the following formula:  In one form all of the R groups are methyl. These electrodes appear particularly suitable for use at high voltages in applications such as electric and hybrid electric vehicles.

Organosilicon amine-based electrolytes

Disclosed is a nonaqueous liquid electrolyte comprising poly(siloxane-g-3 ethylene oxide) and its synthesis. This electrolyte provides significant safety, improved electrochemical stability, improved conductivity, lower impedance, and lower manufacturing costs.
