WIPO Patent Application WO/2024/049132
Kind Code:
A1
Abstract:
An electronic device according to various embodiments of the present invention may comprise a battery. The battery may comprise: a pouch; and an electrode assembly included in the pouch and formed by stacking and winding a positive electrode plate disposed on an outermost side, a first separator disposed inside the positive electrode plate, a negative electrode plate disposed inside the first separator, and a second separator disposed inside the negative electrode plate. The positive electrode plate may comprise: a resistive layer; a first conductor layer disposed in a first direction of the resistive layer; a second conductor layer disposed in a second direction of the resistive layer, and comprising a region in which a portion of the second conductor layer is unformed; a first positive electrode coating layer disposed in the first direction of the first conductor layer, and comprising a first region in which a portion of first positive electrode coating layer is unformed; a second positive electrode coating layer disposed in the second direction of the second conductor layer, and comprising a first region in which a portion of the second positive electrode coating layer is unformed; and a first positive electrode tab disposed on the first conductor layer exposed through the first region of the first positive electrode coating layer. The second positive electrode coating layer comprises a second region, in which a portion of the second positive electrode coating layer is unformed, at a location corresponding to the region in which a portion of the second conductor layer is unformed. A portion of the resistive layer may be configured to be exposed to the outside through the region where a portion of the second conductor layer is unformed and a second region where a portion of the second positive electrode coating layer is unformed. Various other embodiments may be possible.
