BATTERY AND ELECTRONIC DEVICE USING THE SAME

A battery includes a packaging shell and a battery cell. The battery cell is disposed in the packaging shell, the battery cell includes a first electrode plate, the first electrode plate includes a first empty foil area and a second empty foil area where no active material is disposed on either side of the first electrode plate. The first empty foil area is arranged on a first surface, the second empty foil area is arranged on a second surface. At least one of the first surface and the second surface is adhered to the packaging shell by a bonding member. In a width direction of the battery cell, a width of the battery cell is W, a width of the first empty foil area is W1, a width of the second empty foil area is W2, and 0≤ (W1+W2)/W≤40%.
