The composites could then be formed into solid - state microsupercapacitors with no need for current collectors, binders or separators. (sciencedaily.com)
No backing metal current collector is needed like for LIB and supercaps (a cost and weight saving). (judithcurry.com)
This design also eliminates the polymeric binders and copper current collector foil used in a traditional battery electrode.» (sciencedaily.com)
