| titleOfInvention | A separator having porous coating layer and electrochemical device containing the same |
| abstract | The present invention relates to a nonwoven fabric substrate; And a porous coating layer comprising inorganic particles and a polymeric binder formed on at least one side of the nonwoven fabric substrate, wherein the inorganic particles have a mean particle size of 100 nm or more and 1000 nm or less and Wherein the second inorganic particles having an average diameter of 1/20 or more and less than 1/10 of the first inorganic particles are mixed in a weight ratio of 60:40 to 99: 1. Even when the electrochemical device is overheated by the porous coating layer, such a separator can prevent a short circuit between the positive electrode and the negative electrode by the inorganic particles existing in the porous coating layer. In addition, by using inorganic particles having different particle sizes, it is possible to prevent the occurrence of leakage current without increasing the loading amount of the porous coating layer and to increase the phase stability of the coating slurry. Therefore, the electrochemical device having such a separator is not only excellent in thermal stability, but also can be realized in a high capacity. |
