Title (EN) ELECTROLYTE FOR LITHIUM SECONDARY BATTERY AND LITHIUM SECONDARY BATTERY COMPRISING SAME
(FR) ÉLECTROLYTE POUR PILE RECHARGEABLE AU LITHIUM ET PILE RECHARGEABLE AU LITHIUM LE COMPRENANT
(KO) 리튬 이차전지용 전해액 및 이를 구비한 리튬 이차전지
Abstract: front page image
(EN)The present invention relates to an electrolyte for a lithium secondary battery containing lithium salt and an organic solvent and a lithium secondary battery comprising same, wherein the electrolyte further comprises a solid salt containing one anion selected from a hexafluorophosphate anion (PF6-) and a tetrafluoroborate anion (BF4-) and a pyridinium-based cation. According to the present invention, the lithium secondary battery having improved high-temperature life characteristics can be provided by providing the electrolyte containing the additives.
(FR)La présente invention concerne un électrolyte pour pile rechargeable au lithium contenant un sel de lithium et un solvant organique et une pile rechargeable au lithium le comprenant, l'électrolyte comportant en outre un sel solide contenant un anion choisi parmi l'anion hexafluorophosphate (PF6 -) et l'anion tétrafluoroborate (BF4 -) et un cation à base de pyridinium. Selon la présente invention, une pile rechargeable au lithium présentant de meilleures caractéristiques de durée de vie à haute température peut être obtenue par utilisation de l'électrolyte contenant les additifs.
(KO)본 발명은 리튬염 및 유기용매를 포함하는 리튬 이차전지용 전해액 및 이를 구비한 리튬이차전지에 관한 것으로서, 상기 전해액은 헥사플루오로포스페이트 (hexafluorophosphate) 음이온(PF6-) 및 테트라플루오로보레이트 (tetrafluoroborate) 음이온(BF4-) 선택된 하나의 음이온과 피리디니움(pyridinium)계 양이온을 갖는 고체염을 더 포함하는 것을 특징으로 한다. 본 발명에 따르면, 상기 첨가제를 포함하는 전해액을 제공함으로써 수명특성이 개선된 리튬 이차전지를 제공할 수 있다.
