Fluoro-Compounds in Electrolytes for Energy Storage Devices

1 Results Electrochemical energy storage devices such as lithium-ion batteries1-2] and double-layer capacitors3-4] have attracted a great deal of attention because of their potential application to electric hybrid vehicles. They utilize nonaqueous electrolyte solutions comprising from organic solvents and lithium or quaternary ammonium salts with fluorine-containing anions. This is because the relatively large anions with electron-withdrawing atoms enable ionic dissociation in dipolar aprotic solvents...
