摘要:
A method is provided for producing a battery electrode having a configuration in which a compound material layer containing an active material and a binder is retained on a current collector. This method includes forming protrusions composed of a polymer on a surface of the current collector, forming a binder solution layer by coating a binder solution containing the binder over the polymer protrusions onto the current collector, depositing the binder solution layer and a compound material paste layer on the current collector by applying a compound material paste containing the active material over the binder solution layer, and obtaining an electrode in which the compound material layer is formed on the current collector by drying both the deposited binder solution layer and compound material paste layer.
