BATTERY AND ELECTRIC APPARATUS INCLUDING SAME

A battery includes an electrode assembly, a housing accommodating the electrode assembly, and a first layer including an insulating material. The electrode assembly includes a first electrode sheet and a second electrode sheet that are stacked and adjacently disposed along a fourth direction. The first electrode sheet includes a first edge extending along a first direction, a second edge extending along a second direction perpendicular to the first direction, and a third edge extending along a third direction intersecting both the first direction and the second direction, the third edge including a first end connected to the first edge and a second end connected to the second edge. The first layer is adhered to the first electrode sheet and includes a first border extending along the first direction and a second border extending along the second direction and connected to the first border.
