description The utility model relates to the field of batteries, and discloses a battery cell and a battery. The battery cell comprises a diaphragm as well as first pole pieces (10) and second pole pieces (20) which are alternately arranged, the diaphragm is arranged between the adjacent first pole pieces and second pole pieces, a first tab (11) and a second tab (12) are arranged at the top of each first pole piece at an interval, a third tab (21) is arranged in the middle of the top of each second pole piece, and the diaphragm is arranged between the first pole pieces and the second pole pieces. And the third tab is positioned between the first tab and the second tab at an interval. According to the utility model, the battery cell is provided with the first tab, the second tab and the third tab, so that a charging mechanism with two loops can be formed in the battery, and the purposes of reducing the heat production of the tabs, reducing the temperature rise of the battery and improving the charging capacity of the batt
