  "textContent": "The separator according to the present disclosure and the electrochemical device including the same show low internal resistance between the separator and an electrode. The separator includes heat resistant particles in a heat resistant coating layer. The heat resistant particles include a particle-shaped inorganic material and fluorine (F) doped to a surface of the inorganic particles. When the internal temperature of a battery is increased during the operation of the battery, the separator shows improved heat resistance by virtue of an endothermic effect derived from a phase change of the heat resistant particles. In addition, decomposition of a lithium salt used as an ingredient of electrolyte is inhibited by the fluorine atoms introduced to the heat resistant particles, resulting in improvement of ion conductivity and resistance characteristics. Further, the separator including the heat resistant particles introduced thereto has excellent resistance characteristics and shows high oxidation stability of an electrolyte, resulting in improvement of the electrochemical stability of a battery.",
