Abstract
In at least one embodiment, a battery is provided comprising an electron beam-treated current collector having an increased surface energy compared to an untreated current collector and an electrode disposed on a treated surface of the current collector. The electrode may include a water-soluble binder uniformly coating a surface of the current collector and the treated current collector may have a contact angle with the water-soluble binder of 70 degrees or less. The electron beam treatment may be applied to a moving current collector foil as part of a battery production process, prior to application of an electrode slurry.
