Abstract:
1. A method for producing a supercapacitor, the method comprising: providing first and second substantially planar collectors, having respective first and second collector surfaces facing each other and spaced apart a selected distance apart growing spaced apart first and second arrays of single wall carbon nanotube (SWCNT) towers or multi-wall carbon nanotube (MWCNT) towers directly on the first and second collector surfaces, with no catalyst substance and no binder material deposited on the collector surfaces, the towers having heights in a range of about 10-1000 μm; positioning a porous separator module, having a substantial portion of its pores with diameters in a range 2-50 nm, between and contiguous to the first array and the second array of towers, the separator module having a thickness no greater than a height of a nanotube tower and having a separator module transverse area A(sep) that is substantially equal to a transverse area A(el) of at least one of the first and second collector surfaces; functionalizing at least one MWCNT tower or SWCNT tower to increase surface wettability of the at least one tower.
