Electrode assembly, battery cell, battery, and electrical apparatus

Abstract

The electrode assembly includes: an electrode plate including an electrode plate body and a tab region; and separator disposed on two opposite sides of the electrode plate. The separators each include a covering portion covering the electrode plate body and an exceeding portion connected to the covering portion, the exceeding portion covering a portion of the tab region, where the exceeding portions on the two opposite sides of the electrode plate are at least partially connected to each other and form a bonding portion, or the exceeding portions on the two opposite sides of the electrode plate are at least partially connected to the tab region and form the bonding portion. The electrode assembly enables two separators to envelop the electrode plate in the width direction of the electrode plate. Even if the separators fold, the electrode plate will not be exposed to the outside.
