Abstract: Disclosed is an electronic device according to an embodiment of the disclosure that includes a battery and a battery mounting part that receives the battery therein, in which the battery mounting part includes a base and at least one side surface extending from an edge of the base and a recess area is formed in at least a partial area of the at least one side surface. Besides, it may be permissible to prepare various other embodiments speculated through the specification.

Abstract: A battery includes an electrode assembly including a positive electrode sheet, a separation membrane, and a negative electrode sheet, at least one cover member surrounding at least a part of an outermost region of the electrode assembly, and exterior material accommodating the electrode assembly and the at least one cover member. The at least one cover member has at least a partial area that overlaps and is fixed to the exterior material, and includes a plurality of air gaps permitting impregnation of the electrode assembly by an electrolyte. An electronic device includes a housing, a display accommodated in the housing and having at least part exposed outside the housing, a memory disposed in the housing, a battery accommodated in the housing, and a processor electrically connected to the display, the memory, and the battery. Other various embodiments as understood from the specification are possible.
