摘要： 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.

摘要： A method of manufacturing the all-solid battery includes steps of: forming a cathode layer; forming an anode layer; forming an electrolyte layer between the cathode layer and the anode layer; and forming an insulation layer using a baroplastic polymer at an edge portion of the battery. The step of forming the insulation layer comprises: forming a coating layer through coating of the edge portion of the battery with the baroplastic polymer; and shaping the baroplastic polymer through pressing of the coating layer.

摘要： Disclosed are a method for preparing an active material, the surface of which is modified, using a surface treatment solution and an active material prepared thereby, and more particularly, an active material in which the amount of impurities on the surface thereof is reduced and on the surface of which a metal oxide configured to cut off direct contact with an electrolyte is uniformly disposed by collectively performing both a washing process and a surface treatment process using a surface treatment solution having a novel composition.
