| 摘要 |
The present invention provides a method for producing a battery electrode having a configuration in which an active material layer containing an active material 22 and a polymer material 24 is retained on a current collector 10, the method comprising a step of applying a paste for forming an active material layer 28 containing the active material 22 and the polymer material 24 in a solvent 26, to the current collector 10, and a step of forming an active material layer on the current collector 10 by drying the applied paste 28. An ionic polymer exhibiting cationic or anionic properties in the paste 28 is used as at least one kind of the polymer material 24, and an electric potential having an opposite polarity to that of the ionic polymer 24 is applied to the current collector 10 after the paste 28 has been applied to the current collector 10.
