Abstract
A method of manufacturing a battery includes providing a slurry including carbon nanotubes, a binder, and a solvent. Then, operating an ultrasonic homogenizer to form a suspension including the carbon nanotubes and the binder within the solvent. Then, applying a layer of the suspension to a current collector of the battery. Finally, with the layer of the suspension applied to the current collector, applying an electrode coating of the battery to the layer of the suspension.
