The slurry after coating is relatively loose, and to increase the energy density of lithium batteries, it is necessary to control the thickness of the pole piece.

The coated pole piece is pressed and equalized by hydraulic pressure and counter-rolling method, so as to increase the energy density of the battery.

The flatness of the pole piece will directly affect the effect of the subsequent slitting process, and the uniformity of the active material of the pole piece will indirectly affect the performance of the battery cell.
