description The invention relates to the technical field of battery manufacturing, in particular to a battery pole piece rolling and stacking device and a rolling and stacking method. The battery pole piece rolling and stacking device comprises a positive pole piece unreeling device, a first diaphragm unreeling device, a negative pole piece unreeling device, a second diaphragm unreeling device, a first cutting knife, a second cutting knife, a driving system and a rolling and stacking assembly. A positive pole piece unreeling device, a first diaphragm unreeling device, a negative pole piece unreeling device and a second diaphragm unreeling device are sequentially arranged along the thickness direction of the battery pole piece. And the first cutting knife is arranged at the downstream end of the negative pole piece unreeling device. The second cutting knife is arranged at the downstream end of the positive pole piece unreeling device, and the positive pole piece unreeling device is located at the downstream end of the fir
