Superior lithium storage properties of carbon coated Li2MnSiO4 cathodes
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...
