PROBLEM TO BE SOLVED: To provide a method for manufacturing a negative electrode plate with a negative electrode paste that exhibits excellent filter penetrability and coating properties and requires only a short period of processing time (dispersion time).SOLUTION: A method for manufacturing a negative electrode plate 131 includes the steps of: making a negative electrode paste 60 by dispersing at least a portion of a negative electrode active material 20 and a first thickener 30 that exhibits a viscosity (mPa s) higher than or equal to 5000 and lower than or equal to 10000 in a 1 wt.% solution, in water 10, then adding and dispersing a second thickener 40 that exhibits a viscosity (mPa s) higher than or equal to 1000 and lower than 5000 in a 1 wt.% solution, and then adding and dispersing a binder 50; and forming a negative electrode active material layer 133 by applying the negative electrode paste 60 to negative electrode foil 132. |
