Abstract: front page image
(EN)The present invention relates to a lithium secondary battery comprising a positive electrode, a negative electrode, a separation membrane and a non-aqueous electrolyte, wherein: the positive electrode comprises a positive electrode active material of LiaNixMnyCozO2(a+x+y+z=2, 0.9≤a≤1.1, 0≤x, 0≤y, 0≤z); the non-aqueous electrolyte comprises (i) fluorinated cyclic carbonate, (ii) propionate ester, and (iii) non-halogenated carbonate, the mixture weight ratio (i:ii) thereof being 20:80 to 50:50.
(FR)La présente invention concerne une batterie rechargeable au lithium comprenant une électrode positive, une électrode négative, une membrane de séparation et un électrolyte non aqueux. L'électrode positive comprend un matériau actif d'électrode positive de formule LiaNixMnyCozO2 (a + x + y + z = 2, 0,9 ≤ a ≤ 1,1, 0 ≤ x, 0 ≤ y, 0 ≤ z) ; l'électrolyte non aqueux comprend (i) un carbonate cyclique fluoré, (ii) un ester propionate, et (iii) un carbonate non halogéné, son rapport en poids de mélange (i : ii) étant de 20 : 80 à 50 : 50.
(KO)양극, 음극, 분리막 및 비수 전해액을 구비하는 리튬 이차전지에 있어서, 상기 양극은 LiaNixMnyCozO2(a+x+y+z=2, 0.9≤a≤1.1, 0≤x, 0≤y, 0≤z)인 양극 활물질을 포함하고, 상기 비수 전해액은 (i) 불소화 환형 카보네이트, (ii) 프로피오네이트계 에스테르 및 (iii) 비할로겐화 카보네이트를 포함하며, 이들의 혼합 중량비(i : ii)가 20:80 내지 50:50인 것을 특징으로 하는 리튬 이차전지에 관한 것이다.
