  • Lithium Secondary Battery
    Publication number: 20250210626
    Abstract: A lithium secondary battery may include an electrode assembly including a positive electrode, a negative electrode, and a separator, an electrolyte, and a battery case accommodating the electrode assembly and the electrolyte. The negative electrode includes a negative electrode active material layer containing graphite and a Si/C composite. The positive electrode includes a positive electrode active material layer containing a lithium transition metal oxide represented by Formula 1. The graphite and the Si/C composite are present in a weight ratio of 93.1:6.9 to 99.9:0.1 in the negative electrode active material layer. The electrolyte includes a non-fluorinated saturated cyclic carbonate and a fluorine-based compound in a weight ratio of 40:1 to 40:20, and the fluorine-based compound is present in an amount of 1 wt % to 5 wt % with respect to a total weight of the electrolyte. Li1+x1[Niy1Coz1Mnw1M1v1]O2??[Formula 1] wherein all the variables in Formula 1 are described herein.
