Abstract
Embodiments provide an electrode assembly, a battery cell, a battery, an electrical apparatus, and a manufacturing method and device. In those embodiments, the electrode assembly includes: an electrode plate, including a main portion and at least one protruding portion. The main portion includes a metal substrate and an active material layer coated on a surface of the metal substrate. The protruding portion is connected to the metal substrate. The metal substrate protrudes along a length direction of the electrode assembly. Along a thickness direction of the electrode assembly, a size of at least a part of the protruding portion is greater than a size of the metal substrate. The electrode assembly according to the Embodiments aims to solve a technical problem of severe heat emission of a tab.
