Semi-dry method electrode self-supporting film and method for removing hot rolling texture by using semi-dry method electrode self-supporting film

The invention provides a semi-dry method electrode self-supporting film and a method for removing a hot rolling texture thereof, and the method comprises the following steps: carrying out hot rolling on semi-dry powder A containing polytetrafluoroethylene fibers, an electrode material and an alcohol-water mixed solvent to form a strip-shaped film blank B, and then slitting the strip-shaped film blank B into slices C along a hot rolling direction; and after the slice C is rotated by 90 degrees, a thickness gradient gradual change area is formed through edge rolling, then the thickness gradient gradual change area serves as a lap joint area to be spliced into a long belt D, and cold rolling is conducted to form the semi-dry method self-supporting film. According to the method, in the processes of slitting, edge rolling, edge folding, strip splicing and cold rolling of a strip-shaped film blank B, a longitudinal texture formed through hot rolling is rotated, the final cold rolling direction is perpendicular to t
