The present invention relates to an electrolyte additive, an electrolyte including the same, and a secondary battery. According to the present invention, side reactions inside a battery are suppressed and charging resistance is low to increase charging efficiency and output, an increase in battery resistance can be suppressed even if stored for a long time under high temperature conditions, and gas generation due to decomposition of electrolyte components is also significantly suppressed, thereby having an effect of providing a secondary battery with long life and excellent high-temperature capacity maintenance. 본 발명은 전해액 첨가제, 이를 포함하는 전해액 및 이차전지에 관한 것으로, 본 발명에 따르면 전지 내부의 부반응을 억제하고 충전 저항이 낮아 충전 효율 및 출력이 향상될 수 있고, 고온 조건에서 장시간 보관하더라도 전지의 저항 증가가 억제될 수 있으며, 전해액 성분의 분해에 의한 가스 발생 또한 현저하게 억제되어 장기 수명 및 고온 용량 유지율이 우수한 이차전지를 제공하는 효과가 있다.
