Abstract

The present invention relates to a secondary battery which is excellent in impact resistance, and the secondary battery according to the present invention includes an electrode assembly having a positive electrode, a negative electrode, and a separator disposed between the positive electrode and the negative electrode; an electrolyte; and a battery case accommodating the electrode assembly and the electrolyte, and the secondary battery satisfies Expression (1) below. V p + 0.1 × C / D e ≤ V e ≤ V p + 0.15 × C / D e <img class="EMIRef" id="5f7d3859-1810-4ebf-8db0-3446f57c5414-ia01" /> In Expression (1) above, V<e> is a total volume (mL) of the electrolyte included in the lithium secondary battery, Vp is a total pore volume (mL) of the electrode assembly, C is a battery capacity (Ah), and D<e> is an electrolyte density (g/mL).
