Abstract: A lithium ion battery including a core-shell structured fire extinguishing particle is disclosed. When the battery is overheated to a predetermined temperature, a shell of the fire extinguishing particle coated on one surface or both surfaces of a porous separator is melted, a fire extinguishing material disposed in an inner space of the shell is released into an electrolytic solution of the battery, and as a result, it is possible to prevent the battery from being ignited or exploded even though the battery is overheated. Further, the melted shell clogs pores of the porous separator to block lithium ions from moving, such that the battery is blocked from being driven, thereby preventing the battery from being overheated any more.
