CELL AND ELECTRIC DEVICE

A cell includes an electrode assembly with a positive electrode plate, a negative electrode plate, a positive electrode tab, and a negative electrode tab. The positive electrode plate includes a positive electrode active material region, and the negative electrode plate includes a negative electrode active material region; along a width direction of the positive electrode plate, the positive electrode active material region has a first end and a second end opposite to each other, and the positive electrode tab protrudes from the first end; along a width direction of the negative electrode plate, the negative electrode active material region has a first region extending beyond the first end and a second region extending beyond the second end, the negative electrode tab is connected to the first region, a width of the first region is denoted as E, a width of the second region is C, and E>C.
