This work report the synthesis and electrochemical properties of porous carbon nanofibers composited with lithium manganese silicate (ACNF/Li2MnSiO4) as electrode material for energy storage devices. The obtained samples were characterized by means of X-ray diffraction (XRD), scanning electron microscopy (SEM) and Brunauer-Emmett-Teller analyzer (BET). The electrochemical properties were investigated using cyclic voltammetry (CV), galvanostatic charge-discharge (GCD) and electrochemical impedance spectroscopy (EIS). The benefits of ACNF/Li2MnSiO4 electrode with maximum surface area and high electrical conductivity leading to enhanced the electrochemical performance. The specific capacity of 217.8 F g-1 at 0.25 A g-1 and 176.4 F g-1 at 2 mV s-1 higher than their pure state (ACNF and Li2MnSiO4). Good cycling stability of ACNF/Li2MnSiO4 electrode over 90% was observed after 1500 cycles. The fascinating electrochemical properties of this composite nanostructure makes it a potential candidate for high performance energy storage devices.
