Abstract:
(EN) The present invention provides a non-aqueous electrolyte comprising: an additive which is an isocyanate-based compound comprising a non-aqueous organic solvent, a lithium salt, and a carbon-carbon triple bond; and the isocyanate-based compound comprising a carbon-carbon triple bond. In the case where the isocyanate-based compound additive comprising a carbon-carbon triple bond of the present invention is included in a non-aqueous electrolyte, lifespan properties and high temperature durability may be enhanced, and the internal resistance of a battery may be reduced.
(FR) La présente invention concerne un électrolyte non aqueux comprenant : un additif qui est un composé à base d’isocyanate comprenant un solvant organique non aqueux, un sel de lithium et une triple liaison carbone-carbone ; et le composé à base d’isocyanate comprenant une triple liaison carbone-carbone. Dans le cas où l’additif de composé à base d’isocyanate comprenant une triple liaison carbone-carbone de la présente invention est inclus dans un électrolyte non aqueux, les propriétés de durée de vie et de durabilité à haute température peuvent être améliorées, la résistance interne d’une batterie peut être réduite.
(KO) 본 발명에서는 비수성 유기 용매, 리튬염 및 탄소-탄소 삼중결합을 포함하는 이소시아네이트계 화합물인 첨가제를 포함하고, 상기 탄소-탄소 삼중결합을 포함하는 이소시아네이트계 화합물을 포함하는 것인 비수성 전해액을 제공한다. 본 발명의 탄소-탄소 삼중결합을 포함하는 이소시아네이트계 화합물 첨가제를 비수전해액에 포함하는 경우 수명 특성 및 고온 내구성을 향상시킬 수 있으며, 전지의 내부저항을 감소시킬 수 있다.
