| titleOfInvention | Separator comprising porous coating, method of making same, and electrochemical device comprising same |
| abstract | The separator of the present invention comprises: (a) a nonwoven fabric substrate having pores; (b) a thermoplastic fine powder located in the pores of the nonwoven fabric substrate, the powder having an average diameter smaller than the average diameter of the pores and a melting point below the melting point or decomposition point of the nonwoven substrate; and (c) a porous coating disposed on at least one surface of said nonwoven substrate, said coating comprising inorganic particles polymerized with at least one binder A mixture of substances, the melting point of the binder polymer is higher than the melting point or decomposition point of the thermoplastic fine powder, wherein the inorganic particles are interconnected and fixed by the binder polymer, and the inorganic particles are The interstitial volumes form pores in the coating. According to the present invention, it is possible to obtain a separator with a uniform porous coating, since said porous coating is formed after first filling the macropores in the nonwoven substrate with thermoplastic fine powder. Therefore, by using the non-woven fabric substrate as a separator, it is possible to prevent an increase in the CV interval due to a charging failure or a leak current. In addition, with thermoplastic fine powder, the separator of the present invention has a shut-off function and maintains the stability of the battery through a uniform porous coating even during thermal runaway. |
