Abstract: front page image
(EN)The present invention relates to: a non-aqueous electrolyte solution including a non-aqueous organic solvent, a lithium salt, and a borate-based salt compound represented by Chemical Formula 1; and a lithium secondary battery including the same. According to the present invention, a non-aqueous electrolyte solution is provided including one or more borate-based salt compounds as additives, so that a lithium secondary battery having improved cycle characteristics and high temperature storage stability can be manufactured.
(FR)L'invention concerne une solution électrolytique non aqueuse comprenant un solvant organique non aqueux, un sel de lithium et un composé de sel à base de borate représenté par la formule 1; et une batterie secondaire au lithium comprenant ladite solution. Selon l'invention, la solution électrolytique non aqueuse comprend un ou plusieurs composé(s) de sel à base de borate en tant qu'additif(s), de telle sorte qu'il est possible de fabriquer une batterie secondaire au lithium présentant des caractéristiques de cycle et une stabilité de stockage à température élevée améliorées.
(KO)본 발명은 비수성 유기용매, 리튬염, 및하기 화학식 1로 표시되는 보레이트계 염 화합물을 포함하는 비수계 전해액 및 이를 이용한 리튬 이차전지에 관한 것이다. 본 발명에서는 하나 이상의 보레이트계 염 화합물을 첨가제로 포함하는 비수계 전해액을 제공함으로써, 사이클 특성 및 고온 저장 안정성이 향상된 리튬 이차전지를 제조할 수 있다.
