A novel asymmetric hybrid supercapacitor based on Li2FeSiO4 and activated carbon electrodes

---

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 electrochemical impedance spectroscopy
(EIS). The CV results reveal the typical capacitance behavior of the LFSO/AC cell within the potential range of 0–3 V. The LFSO/AC cell presents a high discharge capacitance (DSC) of 49Fg−1 at a current density of 1mAcm−2 and delivers a specific energy of 43Whkg−1 and a specific power of 200Wkg−1. The cell
exhibits excellent cycleability and greater efficiency over 1000 cycles.
