Specifically, the first tab 121, the second tab 122, the third tab 131 and the fourth tab 132 are located on the same plane so as to connect to the protection plate assembly 20. The first protection circuit board 21 and the second protection circuit board 22 are respectively located on two sides of the plane. The first protection circuit board 21 and the second protection circuit board 22 are approximately perpendicular to the end surface of the cell main body 11, the first tab 121 and the second tab 122 are connected to the first protection circuit board 21 toward a side surface of the second protection circuit board 22, and the third tab 131 and the fourth tab 132 are connected to the second protection circuit board 22 toward a side surface of the first protection circuit board 21.
