Abstract: PURPOSE: A micro encapsulated extinguishing composition is provided to control emission temperature of the extinguishing composition and to stop overcharging and malfunction of a lithium secondary battery during heating due to overcharging and malfunction of the lithium secondary battery. CONSTITUTION: A micro encapsulated extinguishing composition(10) comprises an extinguishing composition(14) and a thermoplastic resin layer(12) formed on the outside of the extinguishing composition. The thermoplastic resin layer is formed of a thermoplastic single polymer or copolymer. The single polymer is formed by polymerization of one monomer. The copolymer is formed by polymerization of two or more monomers. The monomer comprises an ethylene group. The extinguishing composition contains one or two hydrogen atoms and a fluorinated ketone compound with a boiling point of 0-150 °C.
