A novel asymmetric hybrid supercapacitor based on Li2FeSiO4 and activated car…

a b s t r a c t A novel, hybrid supercapacitor is fabricated with Li2FeSiO4 (LFSO) as the negative electrode and activated carbon (AC) as the positive electrode in a standard, non-aqueous 1.0M LiPF6-EC/DMC electrolyte. The electrochemical properties of the LFSO/AC hybrid supercapacitor are investigated by means of cyclic voltammetry (CV), charge/discharge (C/D) measurement and electrochemic…
