The embodiment of the utility model provides an electrode assembly, a battery monomer, a battery and a power utilization device. The electrode assembly comprises a main body part and a plurality of first tabs led out from the main body part, and the plurality of first tabs are stacked. The two adjacent first tabs are at least partially overlapped in the thickness direction of the first tabs. And in the thickness direction, the maximum number of the first tabs which are overlapped at the same time is smaller than the total number of the first tabs. According to the electrode assembly, the number of the first tabs which are simultaneously overlapped in the thickness direction is reduced, so that the difficulty of connecting the first tabs to other conductive structures is reduced, more first tabs can be arranged on the electrode assembly, and the overcurrent capacity of the electrode assembly is improved. 本申请实施例提供一种电极组件、电池单体、电池以及用电装置。电极组件包括主体部和从主体部引出的多个第一极耳，多个第一极耳层叠设置。在第一极耳的厚度方向上，相邻的两个第一极耳至少部分地重叠。在厚度方向上，同时重叠的第一
