Abstract:
(EN) The present invention can provide an electrolyte additive comprising a lithium compound for film formation and a salt of an anion, derived from a nitrogen-atom-containing compound, and Cs+ or Rb+. The present invention also provides a nonaqueous electrolyte comprising a lithium salt, a nonaqueous organic solvent, and the electrolyte additive, wherein the electrolyte additive may further comprise lithium difluorobisoxalatophosphate, and can provide a lithium secondary battery comprising: a positive electrode comprising a positive active material; a negative electrode comprising a negative active material; a separator interposed between the positive electrode and the negative electrode; and the nonaqueous electrolyte. A secondary battery comprising the electrolyte additive according to the present invention can have an improved high-temperature output characteristic.
(FR) La présente invention peut fournir un additif d'électrolyte comprenant un composé de lithium destiné à la formation de film et un sel d'un anion, dérivé d'un composé contenant un atome d'azote, et Cs+ ou Rb+. La présente invention concerne également un électrolyte non aqueux comprenant un sel de lithium, un solvant organique non aqueux et l'additif d'électrolyte, l'additif d'électrolyte pouvant en outre comprendre du difluorobisoxalatophosphate de lithium, et pouvant fournir une batterie secondaire au lithium comprenant : une électrode positive comprenant un matériau actif positif ; une électrode négative comprenant un matériau actif négatif ; un séparateur interposé entre l'électrode positive et l'électrode négative ; et l'électrolyte non aqueux. Une batterie secondaire comprenant l'additif d'électrolyte selon la présente invention peut avoir une caractéristique de sortie à haute température améliorée.
(KO) 본 발명은 질소 원자 함유 화합물 유래 음이온과 Cs+ 또는 Rb+와의 염 및 피막 형성용 리튬 화합물을 포함하는 전해액 첨가제를 제공할 수 있다. 또한, 본 발명은 리튬염, 비수성 유기용매 및 상기 전해액 첨가제를 포함하는 것인 비수성 전해액을 제공하며, 상기 전해액 첨가제는 리튬 디플루오로 비스옥살레이토 포스페이트를 더 포함하는 것일 수 있고, 양극 활물질을 포함하는 양극, 음극 활물질을 포함하는 음극, 상기 양극과 상기 음극 사이에 개재된 분리막 및 상기 비수성 전해액을 포함하는 리튬 이차전지를 제공할 수 있다. 본 발명에 따른 전해액 첨가제를 포함하여 형성된 이차전지는 고온 출력 특성이 향상될 수 있다.
