Title (EN) LITHIUM SECONDARY BATTERY
(FR) ACCUMULATEUR AU LITHIUM
(KO) 리튬 이차 전지
Abstract:
(EN) The present invention relates to a lithium secondary battery comprising: a negative electrode comprising a negative electrode active material containing Si or Sn; a positive electrode comprising a positive electrode active material; and a non-aqueous electrolyte. The non-aqueous electrolyte comprises: a non-aqueous organic solvent; a lithium salt; fluoroethylene carbonate; a first additive containing at least one compound among compounds represented by chemical formulas 1 to 4; and a second additive containing at least one compound among compounds represented by chemical formula 5 or 6.
(FR) La présente invention porte sur un accumulateur au lithium comprenant : une électrode négative comprenant un matériau actif d'électrode négative contenant du Si ou du Sn; une électrode positive comprenant un matériau actif d'électrode positive; et un électrolyte non aqueux. L'électrolyte non aqueux comprend : un solvant organique non aqueux; un sel de lithium; du carbonate de fluoréthylène; un premier additif contenant au moins un composé parmi des composés représentés par les formules chimiques 1 à 4; et un deuxième additif contenant au moins un composé parmi des composés représentés par les formules chimiques 5 ou 6.
(KO) 리튬 이차 전지에 관한 것으로서, 이 리튬 이차 전지는 Si 또는 Sn이 포함된 음극 활물질을 포함하는 음극, 양극 활물질을 포함하는 양극, 및 비수 전해질을 포함하고, 상기 비수 전해질은 비수성 유기 용매, 리튬염, 플루오로에틸렌 카보네이트, 화학식 1 내지 4로 표현되는 화합물 중 적어도 하나를 포함하는 제1 첨가제 및 화학식 5 또는 6으로 표현되는 화합물 중 적어도 하나를 포함하는 제2 첨가제를 포함하는 것이다.
