METHOD FOR MANUFACTURING ULTRACAPACITOR ELECTRODE WITH HIGH DENSITY AND ULTRACAPACITOR CELL USING ULTRACAPACITOR ELECTRODE MANUFACTURED THEREBY

摘要

The present invention relates to a method for manufacturing an ultracapacitor electrode, which includes a step of adding at least one carbon nanomaterial selected from graphene, a carbon nanotube and a carbon nanofiber, and a silane-based material to a dispersion medium to disperse the carbon nanomaterial, a step of filtering the dispersed materials with a vacuum filter on which follicles are mounted, a step of selectively filtering the carbon nanomaterial with the follicles and sticking the filtered carbon nanomaterial to the follicles in a rubber type electrode form, a step of separating the carbon nanomaterial in the rubber type electrode form from the follicles and drying the separated carbon nanomaterial, and a step of punching the dried material into a desired size, and an ultracapacitor cell using the ultracapacitor electrode manufactured thereby. According to the present invention, the ultracapacitor electrode having improved lifespan characteristics that requires only the carbon nanomaterial that is an electrode active material and does not require a binder and a conductive material is manufactured. A process is very simple as compared with a coating method or a rolling method for forming an electrode, and durability can be improved by improving the density of the electrode and an irreversible capacity can be reduced by minimizing an electron movement path loss.;COPYRIGHT KIPO 2016
