The present invention relates to a lithium battery comprising a cathode, an anode, a separator interposed therebetween, and an organic electrolyte solution, wherein the battery is not contained in a packaging film made of a polymer film which is not reactive with the organic electrolyte solution and melts at 90 to 130 ° C. Provided is a lithium battery comprising a pack in which a safe aromatic substance that suppresses an exothermic reaction is sealed in an amount of 5 to 30% by weight based on the total weight of the organic electrolyte solution.n n n The battery manufactured according to the present invention includes a pack containing a safety enhancing material inside the battery to suppress the exothermic reaction, and the material does not affect the battery performance during normal operation of the battery, but in case of emergency An internal safety enhancing substance is released from the pack to suppress the abnormal exothermic reaction, thereby improving the safety of the battery. |
