An antistatic composition comprises (a) at least one ionic salt consisting of a nonpolymeric nitrogen onium cation and a weakly coordinating fluoroorganic anion, the conjugate acid of the anion being a superacid; and (b) at least one thermoplastic polymer. The composition exhibits good antistatic performance over a wide range of humidity levels.

Antistatic composition

Novel sulfonylinide and sulfonylmethide compounds are described which are useful as conductive salts. Also described is the use of the above compounds in salt form in battery electrolytes, particular salts having mixed perfluorocaron and hydrocarbon groups or having all hydrocarbon groups. The above salts are less expensive to produce and still exhibit excellent conductivity and low corrosivity.

Sulfonylimide compounds

Amide and methide salts, comprising in the case of an amide salt one cyano (&mdash;CN) group, and in the case of a methide salt, two cyano groups are described in applications requiring a high degree of ionic dissociation. The salts are especially useful as electrolyte components in electrochemical cells such as batteries, fuel cells, capacitors, supercapacitors, electrochemical sensors and electrolytic cells, by providing a means for ionic conduction and transport.

Cyano-substituted methide and amide salts

Electrolyte compositions and electrochemical systems containing such compositions are described where the electrolyte includes in a matrix material a combination of a conductive salt and a bis(perfluoroalkanesulfonyl)imide surfactant salt. The compositions improve wettability of electrodes and separators while maintaining and improving conductivity, stability, and compatibility with other cell components.

Bis (perfluoralkanesulfonyl)imide surfactant salts in electrochemical systems

A method for preparing fluoroalkylsulfonyl imides by reacting a fluoroalkylsulfonamide with a fluoroalkylsulfonyl halide or a fluorosulfonyl halide in the presence of a non-nucleophilic base. One reaction is:
