Title:
PRODUCTION METHOD FOR SHEET-LIKE ELECTRODE MOLDING
Document Type and Number:
WIPO Patent Application WO/2024/024785
Kind Code:
A1
Abstract:
This production method for a sheet-like electrode molding comprises a step for forming an electrode material film on a support body by using an electrode material which includes an electrode active material and which has a solid component concentration of 30 vol.% or more. The electrode material film is formed by: causing a blade which has a shape where the widthwise opposite end parts project more prominently as compared to the widthwise center part and in which said widthwise center part is vibrating, to relatively move along the surface of the support body while keeping a constant distance between the surface of the support body and the blade; restricting the thickness of the electrode material supplied on the support body, by means of a gap between the widthwise center part of the blade and the surface of the support body; and restricting the width of the electrode material by means of the widthwise opposite end parts projecting more prominently as compared to the widthwise center part of the blade.
