Provided are an additive represented by Chemical Formula 1, an electrolyte for a lithium secondary battery including the same, and a lithium secondary battery. The details of Chemical Formula 1 are as set forth in the specification.

Additive, and lithium secondary battery electrolyte and lithium battery which comprise same

Provided is an electrolyte for a lithium secondary battery, the electrolyte including a non-aqueous organic solvent, a lithium salt, and an additive, wherein the additive includes a compound represented by Chemical Formula 1. The definitions of each of the substituents in Chemical Formula 1 are as set forth in the detailed description.

Electrolyte for lithium secondary battery and lithium secondary battery comprising same

An electrolyte for a rechargeable lithium battery includes a non-aqueous organic solvent, a lithium salt, and an additive, wherein the additive includes a compound represented by Chemical Formula 1 and a compound represented by Chemical Formula 2: wherein X is a fluoro group, a chloro group, a bromo group, or an iodo group, and A is a C1 to C10 alkylene group or (—CH—O—CH—), wherein m is an integer of 1 to 10.

Electrolyte for rechargeable lithium battery and rechargeable lithium battery

The present invention relates to a lithium secondary battery. The lithium secondary battery includes a positive electrode including a positive active material; a negative electrode including a negative active material; and an electrolyte including a non-aqueous organic solvent, a lithium salt, and an additive including a compound represented by Chemical Formula 1. The negative active material includes Si at about 0.1 wt % to about 32 wt % in amount based on a total weight of the negative active material.
