    Lithium transition metal silicates, Li2MSiO4 (M = Fe, Mn, Co),(1) have attracted a lot of interest recently as positive electrodes for Li-ion batteries due to their potentially high theoretical ... capacities and to their rich crystal chemistry as they undergo complex polymorphism. Polymorphs of these ĆtetrahedralĆ structures can be classified into low- and high-temperature forms, which differ in the ordering/distribution of cations within tetrahedral sites of a hexagonal close-packed-based arrangement of oxygen.(2) Recent progress in the structure determination of Li2MSiO4 polymorphs(2) paves the way for a detailed study of the mechanisms of Li extraction/insertion from/into these silicates as a function of local and/or long-range order of cations. The achievements in the synthesis of electrochemically active Li2FeSiO4 (small, carbon-coated particles) prompted us to study in detail their electrochemical properties as a function of the crystal structure adopted.
