Abstract: A rolling apparatus includes a roller assembly and a power source. The roller assembly includes four rollers, where the four rollers (110a) are arranged side by side in pairs along a first direction and a second direction intersected with each other, and two rollers arranged side by side define a roll gap therebetween. The power source drives two rollers arranged diagonally to rotate in a same direction around their axes. Two roll gaps defined by one of the two rollers arranged diagonally and the two rollers arranged side by side therewith are used for rolling a first electrode plate twice, and two roll gaps defined by the other one of the two rollers arranged diagonally and the two rollers arranged side by side therewith are used for rolling a second electrode plate twice. In the rolling apparatus, the four rollers form strip moving routes.
