Claim 15:
16. A battery, comprising a housing and an electrode assembly, the housing accommodates the electrode assembly, and the electrode assembly comprising:
a first electrode plate;
a second electrode plate, wherein a polarity of the second electrode plate is opposite to a polarity of the first electrode plate; and
a separator disposed between the first electrode plate and the second electrode plate;, wherein,
the electrode assembly is formed by winding the first electrode plate, the separator, and the second electrode plate;
a plurality of first tab units and a plurality of second tab units are disposed on the first electrode plate, and a plurality of third tab units are disposed on the second electrode plate; and
in a thickness direction of the electrode assembly:
the plurality of first tab units are stacked to form a first tab, the plurality of second tab units are stacked to form a second tab, and the plurality of third tab units are stacked to form a third tab;
projections of the first tab, the second tab, and the third tab on a projection plane perpendicular to the thickness direction of the electrode assembly are spaced apart from each other, and
a projection of the third tab on the projection plane is located between a projection of the first tab and a projection of the second tab.
