According to an embodiment of the present disclosure, a separator is provided which includes a porous substrate; and an inorganic particle layer which is placed on one or both surfaces of the porous substrate and includes inorganic particles and an inorganic binder, wherein the inorganic particle layer includes an organic compound having a lower content than the inorganic binder and the inorganic binder includes a metal silicate.
Claims17
A separator comprising:
- a porous substrate;
- and
- an inorganic particle layer which is placed on one or both surfaces of the porous substrate and includes inorganic particles and an inorganic binder, wherein the inorganic particle layer further includes an organic compound having a lower content than the inorganic binder and the inorganic binder includes a metal silicate.
A separator comprising:
- a porous substrate having first and second large surfaces opposite to each other;
- and
- an inorganic particle layer securely adhered to at least one of the first and second large surfaces of the porous substrate,
- wherein the inorganic particle layer comprises inorganic particles, a metal silicate binder, and an organic compound, and
- wherein a content of the organic compound in the inorganic particle layer is less than a content of the metal silicate binder.
