Li2FeSiO4 is deemed to be a potential candidate for large-scale applications because of its abundance,low cost and high safety,etc.Unfortunately,its low conductivity,resulting in poor rate performance,has become a mai...
In this paper, Li2FeSi0.98M0.02O4/C(M = Mg, Zn, Co, Mn, Ni) was synthesized as cathode material for lithium ion battery by solid-state method. The results show that the materials doped with Mg and Zn at the Si-sites h...
