  "textContent": "The present invention aims to improve the fire resistance of an electrolytic solution used for a lithium-ion battery and improve the life characteristics of the lithium-ion battery. In the lithium ion battery of the present invention, specific amounts of ethylene carbonate and dimethyl carbonate are used for a non-aqueous electrolytic solution, and trimethyl phosphate is added thereto. Specifically, the non-aqueous electrolytic solution contains 60 vol% or more of ethylene carbonate (EC) and dimethyl carbonate (DMC). The volume ratio of DMC to the sum of EC and DMC is 0.3 to 0.6, and the non-aqueous electrolytic solution contains 3 to 5 wt% of trimethyl phosphate (TMP) with respect to the total weight of the non-aqueous electrolytic solution. Such a non-aqueous electrolytic solution has an effect of improving the self-fire extinguishing property, and thus improves the safety of the lithium-ion battery.",
