In the present paper, we describe utilization of cathode active material as anode active material, for example, Li2MnSiO4. The lithium manganese silicate has been successfully synthesized by solid-state reaction method. The X-ray diffraction pattern confirms the orthorhombic structure with Pmn2 1 space group. The Li/Li2MnSiO4 cell delivered the initial discharge capacity of 420 mA h g−1, which is 110 mA h g−1 higher than graphitic anodes. The electrochemical reversibility and solid electrolyte interface formation of the Li2MnSiO4 electrode was emphasized by cyclic voltammetry.
