Spherical lithium ion battery anode material and preparation method of precursor thereof

The invention relates to a spherical lithium ion battery anode material and a preparation method of a precursor thereof. The preparation method comprises the following steps of: with newly-prepared nano flaky nickel hydroxide as a raw material, dispersing the raw material in an aqueous solution, adding a certain proportion of cobalt salt into the aqueous solution, reacting for several hours in an enclosed vessel to obtain uniform spherical granules which can be used as a precursor for preparing the lithium ion battery anode material; and uniformly mixing the obtained precursor granules and a lithium salt and carrying out high-temperature calcining to finally obtain the spherical lithium ion battery anode material with uniform granule size. The preparation method disclosed by the invention is simple to operate, high in efficiency, easy in obtainment of raw material, low in cost and environment-friendly; and the prepared spherical lithium battery anode material has good electrochemical property.
