Effect of electrode mass ratio on aging of activated carbon based supercapaci…

a b s t r a c t The accelerated degradation of carbon based supercapacitors utilizing 1MEt4NBF4 in acetonitrile and in propylene carbonate as electrolyte is investigated for a constant cell voltage of 3.5V as a function of the positive over total electrode mass ratio. The degradation rate of the supercapacitor using acetonitrile as a solvent can be decreased by increasing the mass of the posi…
