Zusammenfassung:	The present invention relates to an electrolyte additive for a secondary battery to protect electrodes and increase performance of the secondary battery, an electrolyte including the same, and a secondary battery including the same. According to an embodiment of the present invention, the electrolyte additive for a secondary battery comprises a compound represented by the following formula (1), wherein R1 and R2 are the same as each other or different, each independently hydrogen, or a C1 to C3 alkyl group, and X is a halogen element and is substituted in at least one of ortho, meta, and para positions of a benzene ring. 본 발명의 실시예를 따르는 이차전지용 전해질 첨가제는 하기 화학식 1 로 표시되는 화합물을 포함한다. [화학식 1] JPEGpat00016.jpg3526 (상기 화학식 1에서, 상기 R1 및 R2는 서로 동일하거나 상이하고, 각각 독립적으로 수소, 또는 C1 내지 C3인 알킬기이다. 또한, 상기 X는 할로겐 원소이고, 벤젠 고리의 올쏘(orth), 메타(meta) 및 파라(para) 위치 중 적어도 어느 하나 이상의 위치에 치환된다.).
