An additive for an electrolyte of a lithium secondary battery, the additive including a polysiloxane-based compound represented by Formula 1 below: In formula 1 R1, R2, R3, A1, A2, l, m, n, o and p are as described in the detailed description of the present invention.
摘要:
An organic electrolytic solution includes a lithium salt; an organic solvent containing a high dielectric constant solvent and/or a low boiling point solvent; and a glycidyl ether compound represented by Formula 1: where, n, R1, R2, R3, R4, R5, R6 and A are described in the detailed description. In conventional organic electrolytic solutions, irreversible capacity is increased due to decomposition of a polar solvent. A lithium battery employing the organic electrolytic solution has excellent charge/discharge characteristics by inhibiting cracks of a negative electrode active material which occur during charging and discharging of the battery. Therefore, the lithium battery can have high stability, reliability and charge/discharge efficiency.
