Disclosed herein are an electrolyte for a lithium secondary battery and a lithium secondary battery including the same. The disclosed lithium secondary battery includes: a cathode; an anode; a separator interposed between the cathode and the anode; and an electrolyte, wherein the electrolyte includes: a lithium salt; and a solvent including a perfluorinated ether-based solvent, fluoroethylene carbonate (FEC), and ethylmethyl carbonate (EMC).

Electrolyte for lithium secondary battery and lithium secondary battery containing same

Disclosed is a lithium secondary battery having an improved lifetime. The lithium secondary battery may include: a cathode including a cathode active material; an anode including an anode active material; a separator disposed between the cathode and the anode; and an electrolyte including bis(trimethylsilyl) 2,2-thiodiacetate.

Lithium secondary battery

Disclosed is a lithium secondary battery capable of preventing the battery life from being reduced. The lithium secondary battery includes a cathode, an anode including silicon, a separator positioned between the cathode and the anode, and an electrolyte including flouoroethylene carbonate (FEC), wherein a weight ratio of the silicon to the FEC is about 0.4 to about 0.8.
