Abstract. Nanoscale carbon-coated Li2MnSiO4 powder is prepared using a conventional solid-state method and can be used as the negative electrode in a Li2MnSiO4/activated carbon (AC) hybrid supercapacitor. Carboncoated Li2MnSiO4 material presents a well-developed orthorhombic crystal structure with a Pmn21 space group, although there is a small impurity of MnO. The maximum specific capacitan…
Abstract. 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 imp…
