Abstract: Li2MnSiO4 is synthesized by solid state reaction method under the optimized conditions of 900oC in Ar atmosphere. Here, adipic acid is used as the source material for carbon. Powder X-ray diffraction measurements confirm the Li2MnSiO4 phase formation. The Li/Li2MnSiO4 cell delivers initial discharge capacity of 160 mAh g–1 at C/20 rate. After a few initial cycles, the cell exhibits a stable discharge behavior ∼140 mAh g–1 with coloumbic efficiency over 90%. For the first time, we observed such stable discharge behavior for Li2MnSiO4 electrodes. Thus, improved stability is due to proper optimization of the compound as well as the source material for carbon.
