摘要
Provided are a separator for early checking a low voltage failure, a secondary battery comprising the same, and a method for early checking a low voltage failure using the same. The separator includes a porous substrate having a plurality of pores; and a porous coating layer which is formed on both surfaces of the porous substrate and includes a plurality of inorganic particles and a binder polymer disposed on at least a part of the surface of the inorganic particles to connect and fix the inorganic particles. The porous substrate comprises a single layer of an electrically conductive substrate or a composite layer where at least one electrically conductive substrate and at least one insulating substrate are alternately laminated.
