ELECTROCHEMICAL APPARATUS AND ELECTRIC DEVICE INCLUDING SAME

An electrochemical apparatus includes a housing, an electrode assembly, a first insulating layer, and an electrolyte, where the electrode assembly and the electrolyte are accommodated in the housing. The electrode assembly includes a plurality of electrode plates stacked along a first direction and a first separator disposed between the plurality of electrode plates. The electrode assembly further includes a first surface and a second surface opposite each other in the first direction, and a first end face connecting the first surface and the second surface. The first insulating layer is adhered to the first surface, the second surface, and the first end face. The first separator includes a substrate layer and a plurality of first coatings spaced apart on a surface of the substrate layer facing an adjacent electrode plate.
