Abstract:
(EN) An electrolyte for a lithium battery and a lithium battery comprising the same are disclosed. The electrolyte for a lithium battery comprises: a non-aqueous organic solvent; and a lithium salt containing lithium hexafluorophosphate (LiPF6), lithium bis(fluorosulfonyl)imide (LiFSI), and lithium tetrafluoroborate (LiBF4), wherein on the basis of 1 mole of LiPF6, the content of LiFSI is 0.01 to 1.2 mole and the content of LiBF4 is 0.05 to 0.7 mole. By using the electrolyte for a lithium battery, service life characteristics and high temperature characteristics of the lithium battery can be improved.
(FR) L'invention concerne un électrolyte pour batterie au lithium et une batterie au lithium comprenant cet électrolyte. Cet électrolyte pour batterie au lithium comprend : un solvant organique non aqueux; et un sel de lithium contenant de l'hexafluorophosphate de lithium (LiPF6), du bis(fluorosulfonyl)imide de lithium (LiFSI) et du tétrafluoroborate de lithium (LiBF4). Sur la base de 1 mole de LiPF6, la teneur en LiFSI est comprise entre 0,01 et 1,2 mole et la teneur en LiBF4 est comprise entre 0,05 et 0,7 mole. L'utilisation de cet électrolyte pour batterie au lithium permet d'améliorer les caractéristiques de durée de vie et les caractéristiques à haute température de la batterie au lithium.
(KO) 리튬 전지용 전해액 및 이를 포함하는 리튬 전지가 개시된다. 상기 리튬 전지용 전해액은 비수성 유기 용매; 및 리튬 헥사플루오로 포스페이트(LiPF 6), 리튬 비스(플루오로설포닐) 이미드(LiFSI), 및 리튬테트라플루오로보레이트(LiBF 4)를 포함하는 리튬염;을 포함하고, LiPF 6 1몰(mole) 기준으로, LiPF 6 1몰(mole) 기준으로, LiFSI의 함량이 0.01몰 내지 1.2몰이고, LiBF 4의 함량이 0.05몰 내지 0.7몰이다. 상기 리튬 전지용 전해액은 사용함으로써 리튬 전지의 수명 특성 및 고온 특성이 개선될 수 있다.
