| Zusammenfassung: | The present application relates to a multilayer separator and a device using the same. Specifically, the present application provides a multilayer separator comprising at least one first porous substrate and at least one second porous substrate, wherein the peeling strength between the first porous substrate and the second porous substrate is in a range of 2 N/m to 50 N/m, and the first porous substrate has an obturator temperature of lower than 135° C. The multilayer separator provided by the present application can effectively guarantee the safety and electrochemical performance of the electrochemical device. |
