Title (EN) ELECTROLYTE FOR LITHIUM SECONDARY BATTERY AND LITHIUM SECONDARY BATTERY COMPRISING SAME
(FR) ÉLECTROLYTE POUR BATTERIE RECHARGEABLE AU LITHIUM ET BATTERIE RECHARGEABLE AU LITHIUM COMPRENANT CELUI-CI
(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 and a lithium secondary battery comprising same, wherein the electrolyte contains lithium salt and an organic solvent, and wherein the electrolyte further comprises a solid salt containing one type of cation selected from ammonium-based cations and an azide anion (N3-). According to the present invention, the lithium secondary battery having improved high-temperature preservation characteristics can be provided by providing the electrolyte containing the additives.
(FR)La présente invention concerne un électrolyte pour une batterie rechargeable au lithium et une batterie rechargeable au lithium comprenant celui-ci. Ledit électrolyte contient un sel de lithium et un solvant organique, et ledit électrolyte comprend en outre un sel solide contenant un type de cations sélectionné parmi des cations des base d'ammonium et un anion azide (N3 -). Ladite batterie rechargeable au lithium présente des caractéristiques améliorées de préservation à haute du fait de l'utilisation de l'électrolyte contenant les additifs.
(KO)본 발명은 리튬염 및 유기용매를 포함하는 리튬 이차전지용 전해액에 관한 것으로서, 상기 전해액은 암모늄(ammonium)계 양이온 중 선택된 1종의 양이온과 아지드 음이온(N3-)을 갖는 고체염을 더 포함하는 것을 특징으로 하는 리튬 이차전지용 전해액 및 이를 구비한 리튬이차전지에 관한 것이다. 본 발명에 따르면, 상기 첨가제를 포함하는 전해액을 제공함으로써 고온 보존특성이 개선된 리튬 이차전지를 제공할 수 있다.
