EDLC Electrode active material for electric double layer capacitor
The present invention relates to a method to manufacture an electrode active material for an electric double layer capacitor (EDLC), in which an active charcoal powder, a conductive additive powder, and a binder powder are manufactured in a granular shape such that the conductive additive powder is uniformly coated and coupled when the active charcoal powder and the conductive additive powder are coated on a surface of a current collector, thereby preventing equivalent series resistance (ESR) characteristic from being degraded. According to the present invention, the method to manufacture an electrode active material for an EDLC comprises: a step of preparing an active charcoal material; a step of preparing a conductive additive powder; a step of preparing a binder powder; a step of mixing 85 to 95 wt% of the active charcoal powder, 3 to 10 wt% of the conductive additive powder, and 2 to 5 wt% of the binder powder by a nanoset mill or a ball mill; and a step of, when the active charcoal powder, the conductive additive powder, and the binder powder are mixed, drying the mixture in a spray drying method so as to manufacture a granular electrode powder.
