Ternary transition metal carbonates have been demonstrated as high-capacity anode materials for lithium-ion batteries owning to their high energy density in lithium storage via a conversion reaction[1].It is well known that Mn owns perfect cycle life and safety, Ni offers high lithium storage capacity but poor thermal stability, while Co offers an enhanced electronic conductivity, contributing to an excellent lithium storage capability[2].Therefore, theoretically speaking,MnxCoxNizCO3(x+y+z=1) should have a good cycle performance taking advantages of Mn, Co and Ni. Ternary transition metal carbonates can also serve as versatile precursors for preparing of oxides as anode materials and lithium-containing cathode materials for lithium-ion batteries. The holistic properties of MnxCoyNizCO3 material strongly depend on the percent of metal elements(Mn,Co,Ni) and the morphology of the sample[3].
