Mechanism can also improve the quality of the continuous pole piece for setting coating.Pole piece can be the pole piece of electrochemical energy storage device.Electrochemical energy storage
Device can be secondary cell or ultracapacitor.Secondary cell is lithium rechargeable battery, sodium ion secondary battery or zinc ion
Secondary cell.
Secondly the rolling device according to the utility model second aspect is illustrated.
Reference picture 8 is to Figure 11 B, according to the rolling device of the utility model second aspect, including：Roller press mechanism 1, including phase
To the pressure roller 11 and back flow roll 12 of setting, for carrying out roll-in to material material 4.Wherein, the rolling device also includes：According to this practicality
Drawing mechanism 2 described in new first aspect item, it is arranged on the upstream and/or downstream of roller press mechanism 1.
Reference picture 8 is to Figure 11 A, and in one embodiment, the rolling device also includes：Roller 3 is pressed against, positioned at roller press mechanism 1
