NOVELTY - Anode material is a manganese-based on phosphate anode material containing vanadium and titanium, and has sodium-titanium-vanadium-manganese-phosphate complex of formula of: Na3+delta+(4-n)x+2yTi1-delta-x-yMn+xVdeltaMn1+y(PO4)3 (I), is new. USE - The anode material is used for sodium ion battery (claimed) e.g. secondary rechargeable lithium ion battery used as energy storage device. ADVANTAGE - The anode material can obtain higher effective specific capacity, inhibits manganese-rich phosphate anode voltage hysteresis phenomenon, and exhibits high dynamic performance and multiplying power performance. The electrochemical performance of the material is improved. DETAILED DESCRIPTION - Anode material is a manganese-based on phosphate anode material containing vanadium and titanium, and has sodium-titanium-vanadium-manganese-phosphate complex of formula of: Na3+delta+(4-n)x+2yTi1-delta-x-yMn+xVdeltaMn1+y(PO4)3 (I), is new. An INDEPENDENT CLAIM is included for a a preparation method of the anode material, involving mixing the raw material of the anode material with a solvent to obtain a precursor, drying the precursor and then sintering to obtain the anode material. Mn+ = Li+, K+, Mg2+, Ca2+, Sr2+, Zn2+, Co2+, Ni2+, Cu2+, Al3+, Cr3+, Fe3+, Y3+, La3+, Ga3+, Zr4+, Sn4+, Nb5+ or W6+; x and y = 0-0.5; delta = 0-0.5; n = greater than or equal to1.
