A novel approach to employ Li2MnSiO4 as anode active material for lithium batteries

Abstract

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 Pmn21 space group. The Li/Li2MnSiO4 cell delivered the initial discharge capacity of 420 mAhg−1, which is 110 mAhg−1 higher than graphitic anodes. The electrochemical reversibility and solid electrolyte interface formation of the Li2MnSiO4 electrode was emphasized by cyclic voltammetry.
