Electronic device including battery

Abstract

An electronic device including a battery is disclosed. According to an example embodiment, the electronic device may include: a housing, a printed circuit board (PCB) disposed inside the housing, and a battery disposed inside the housing and configured to supply power to the electronic device. The battery may include: an electrode assembly including a plurality of substrates having a surface coated with a mixture layer, the plurality of substrates being stacked and insulated through a separator and including a pouch in which the electrode assembly is disposed, a protective frame disposed in the pouch and configured to protect the electrode assembly from an external impact, and a protection circuit module (PCM) comprising circuitry connected to the battery cell and electrically connected to the PCB. The protective frame may include: a central portion disposed to cross an inside of the electrode assembly in a direction perpendicular to a stacking direction of the substrates, and at least one cover connected to at least one end of the central portion and extending in a direction parallel to the stacking direction to surround at least a portion of an outer surface of the electrode assembly.
