Abstract
A method of manufacturing a negative electrode plate for a non-aqueous secondary battery is disclosed, in which it is possible to assess whether or not a binder is localized in an electrode surface without lowering the productivity of the negative electrode plate. The method includes coating an electrode mixture containing at least a negative electrode active material and a binder to a current collector and drying the coated electrode mixture. The method includes an inspection step of measuring a reflectance of a coating surface of the negative electrode plate to thereby determine the quality of the negative electrode plate. If the reflectance of the coating surface of the negative electrode plate falls within a range of 15 to 35% when an incident angle and a light receiving angle each fall within the range of 80° to 90°, the negative electrode plate is determined to be excellent.
