Hello,
I am researching electrochemistry and supercapacitors seem very interesting to me, but poorly I don’t find very much research on really high-capacitance metal-oxide free ones. So I wanted to ask what were the highest capacitance values ever achieved in a metal oxide-and hydroxide free type? I am searching for 500F/g and ascending.
thanks a lot
It depend upon the material used . the way of design carried out . For carbon 500 F/g is achieved. But, inpractical the company claims only 50 F/g
Capacitance depends on various factors including morphology, surface area, pore volume and size, electrolyte, potential applied, active material loading. In case of metal oxides, it also depends on work function of MO, crystal structure, lattice orientation, defects/vacancies, surface chemistry etc. See more details in the following paper
"Supercapacitor performance evaluation"
Unfortunately, there is no standard protocol to report electrochemical performance in Supercapacitors.
