Abstract
The present disclosure relates to an electrode rolling apparatus including a non-coating portion pressing unit that rolls a non-coating portion of an electrode substrate and an electrode rolling method using the same, and can prevent a swell from occurring in the non-coating portion region during the process of rolling the electrode substrate and increase the efficiency of the manufacturing process.
Claims17
An electrode rolling apparatus that rolls an electrode substrate comprising a current collector layer and an electrode mixture layer formed on one surface or both surfaces of the current collector layer,
- wherein the electrode rolling apparatus comprises a non-coating portion pressing unit that presses the non-coating portion region of the electrode substrate to form a pattern;
- and
- an electrode rolling unit that rolls the electrode substrate,
- wherein the non-coating portion pressing unit is arranged subsequent to the electrode rolling unit along an advancing direction of the electrode substrate.
An electrode rolling method that rolls an electrode substrate comprising a current collector layer and an electrode mixture layer formed on one surface or both surfaces of the current collector layer, the method comprising:
- an electrode rolling step of rolling the electrode substrate, and
- a non-coating portion pressing step of pressing a non-coating portion region of the electrode substrate to form a pattern.
