| 20100021815 | SECONDARY BATTERIES COMPRISING EUTECTIC MIXTURE AND PREPARATION METHOD THEREOF - Disclosed is a secondary battery comprising a cathode, an anode, a separator and an electrolyte, wherein the electrolyte comprises: (a) a eutectic mixture; and (b) a first compound reduced at a higher potential vs. lithium potential (Li/Li+) than the lowest limit of the electrochemical window of the eutectic mixture. The electrolyte uses a eutectic mixture in combination with an additive reduced in advance of the eutectic mixture upon the initial charge to form a solid electrolyte interface (SEI) layer. Therefore, the electrolyte can solve the problem of electrolyte decomposition occurring when using a eutectic mixture alone as an electrolyte for a battery, and thus can prevent degradation of the quality of a battery. | 01-28-2010 |
