The present invention concerns methods for the manufacture of ethylene carbonate substituted with a fluorinated alkoxy group, certain ethylene carbonates substituted with a fluorinated alkoxy group as well as their use as solvent or solvent additive for lithium ion batteries and supercapacitors.

Method for the manufacture of fluorinated cyclic carbonates and their use for lithium ion batteries

Disclosed are electrolyte compositions comprising aryl group containing certain fluorinated carbonate, and batteries, especially batteries having a high nominal voltage, comprising such electrolyte composition.

Electrolyte composition comprising fluorinated carbonate, and battery comprising the same

Disclosed is a method of preparing a positive active material for a lithium battery. The method comprises: depositing a positive active material on an electrode on a substrate (1); and putting metal chips on a metal oxides target and performing a sputtering process, thereby depositing mixed metal-oxides on the positive active material (2). In another aspect, the method comprises: preparing an electrode active material; preparing a precursor solution including the electrode active material; and printing the precursor solution on the substrate, and evaporating a solvent at a temperature of 80-120&#xb0; C.
