Battery including electrode assembly and electronic device including the same

A battery comprising:

• an electrode assembly comprising:
• a cathode comprising:
• a cathode collector,
• a cathode active material layer provided in a first region of a surface of the cathode collector, and
• an insulating layer provided in a second region of the surface of the cathode collector and adjacent to the cathode active material layer;
• an anode comprising an anode collector and an anode active material layer provided in a region of a surface of the anode collector;
• and
• a separator provided between the cathode and the anode, and
• an adhesive layer provided between the insulating layer and the separator,
• wherein a first portion of the separator is adhered to a first surface of the adhesive layer,
• wherein a second portion of the separator is spaced apart from the cathode active material layer in a first direction, and
• wherein the first surface of the adhesive layer is at a level that is the same as a level of a surface of the cathode active material layer in a second direction intersecting the first direction.

An electronic device comprising:

• a housing comprising a front plate, a rear plate, and a bracket enclosing a gap between the front plate and the rear plate;
• a display configured to display information through at least a region of the front plate of the housing;
• and
• a battery mounted in a mounting groove of the bracket,
• wherein the battery comprises an electrode assembly, and
• wherein the electrode assembly comprises:
• a cathode comprising:
• a cathode collector,
• a cathode active material layer provided in a first region of a surface of the cathode collector, and
• an insulating layer provided in a second region of the surface of the cathode collector and adjacent to the cathode active material layer,
• an anode comprising an anode collector and an anode active material layer provided in a region of a surface of the anode collector, and
• a separator provided between the cathode and the anode, and
• wherein a first portion of the separator is adhered to a first surface of the insulating layer,
• wherein a second portion of the separator is spaced apart from the cathode active material layer in a first direction, and
• wherein the first surface of the insulating layer is at a level that is the same as a level of a surface of the cathode active material layer in a second direction intersecting the first direction.
