Abstract
A device for producing an electrode laminate includes a roller configured to press an active material layer-attached current collector layer including a current collector layer and an active material layer disposed on at least one surface of the current collector layer. A diamond-like carbon film having an average roughness of 0.16 μm or less is on a surface of the roller in contact with an active material layer or a press sheet is disposed between the roller and a surface of the active material layer, and a diamond-like carbon film having an average roughness of 0.16 μm or less is on a surface of the press sheet in contact with the active material layer.
Claims9
A device for producing an electrode laminate, comprising:
- a roller configured to press an active-material-layer-attached current collector layer including a current collector layer and an active material layer disposed on at least one surface of the current collector layer;
- and
- a diamond-like carbon film having an average roughness of 0.16 μm or less
- wherein the diamond-like carbon film is on a surface of the roller in contact with the active material layer, or
- a press sheet is disposed between the roller and a surface of the active material layer, and the diamond-like carbon film is on a surface of the press sheet in contact with the active material layer.
A method for producing an electrode laminate, comprising:
- pressing, by a roller, an active-material-layer-attached current collector layer including a current collector layer and an active material layer disposed on at least one surface of the current collector layer,
- wherein a diamond-like carbon film having an average roughness of 0.16 μm or less is on a surface of the roller in contact with the active material layer, or
- a press sheet is disposed between the roller and a surface of the active material layer, and a diamond-like carbon film having an average roughness of 0.16 μm or less is on a surface of the press sheet in contact with the active material layer.
