US 2003/0170547 A1 · Electrolyte comprising non-ionic surfactant and lithium ion battery using the same

Abstract

The present invention relates to an electrolyte comprising non-ionic surfactant and a lithium ion battery using the same, and more particularly, to a non-aqueous electrolyte for a lithium ion battery comprising a fluorine-based non-ionic surfactant. The lithium ion battery prepared according to the present invention uses an electrolyte comprising a fluorine-based non-ionic surfactant that is substituted with various functional groups at the end group as represented by Formula 1, which can improve an interfacial property between an electrolyte and electrodes and impedance properties and exhibits a high capacity and excellent charge/discharge properties.
