This invention relates to electrolyte solution compositions useful in lithium-ion batteries. These electrolytes feature lower volatility than solutions known in the art while retaining excellent battery performance using graphite based negative electrode active materials.

Nonaqueous electrolyte lithium secondary batteries

This invention concerns ionomers comprising monomer units of vinylidene fluoride and monomer units of perfluorovinyl ethers having pendant groups containing fluoroalkyl sulfonyl methide or fluoroalkyl sulfonyl imide derivatives and univalent metal salts thereof, and with the uses of said ionomers in eledrochemical applications, electrochemical capacitors and modified electrodes.

Polyvinylidene fluoride ionomers containing pendant fluoroalkylsulfonyl imide or fluoroalkylsulfonyl methide groups

The invention concerns a process for melt forming conductive compositions comprising ionomers into multi-layer electrochemical cells suitable for use in electrochemical applications such as batteries, fuel cells, electrolysis cells, ion exchange membranes, sensors, electrochemical capacitors, and modified electrodes.

Continuous melt process for fabricating ionically conductive articles

Disclosed are ionomers comprising functionalized polyolefins having fluoroalkyl sulfonate pendant groups and ionically conductive compositions formed therefrom by the addition of solvents.

Ionomers and ionically conductive compositions

This invention concerns ionomers comprising a substantially fluorinated, but not perfluorinated, polyethylene backbone having pendant groups of fluoroalkoxy sulfonic acids and the metal salts thereof, and with the uses of said ionomers in electrochemical applications such as batteries, fuel cells, electrolysis cells, ion exchange membranes, sensors, electrochemical capacitors, and modified electrodes.

Fluorinated ionomers and their uses

Disclosed is a highly conductive polymer electrolyte membrane and a process for producing it. This invention also describes batteries which employ the polymer electrolyte membrane of this invention.

Highly conductive ion exchange polymer and process

This invention concerns substantially fluorinated, but not perfluorinated, ionomers consisting of a polyethylene backbone having pendant groups of fluoroalkoxy sulfonic acids and metal salts thereof. Such ionomers are useful for electrochemical applications.
