The invention relates to a method of preparing anode materials for secondary lithium battery by microwave energy. Oxides, hydroxide or salt raw materials of Co, Ni, Mn, Cr, Ti, V, Sc, Fe and Li are weighed in the ratio Li1+xM1-yM'' omega O4-z (wherein x=-1 SIMILAR 5; y=-1 SIMILAR 1; omega =0 SIMILAR 6; Z=-8 SIMILAR 3; ), the raw materials are homogeneously mixed to produce a precursor body, the precursor body is placed in a thermos container capable of being transmitted by microwave, then placed in a microwave oven having microwave frequency of 0.3 SIMILAR 300 gigahertz (GHz) and microwave wavelength of 1mm SIMILAR 1m, and then heat-synthesized for 1 minute SIMILAR 5 hours at 500 DEG C SIMILAR 1000 DEG C, the anode material for lithium secondary lithium battery with the microwave oven cooling is thus produced . The method saves energy and decreases the loss of lithium in the heat-synthesizing process, so ensures the stability in material component. |
