The invention relates to
titanium acid
lithium battery
cathode material containing rare
metal elements, which comprises a synthesized
lithium titanate material. A or a plurality of rare
metal elements are contained in the
lithium titanate material; the rare
metal elements adopt Zr, Al, La, Ce, Pr, Nd, Sm and Dy or Ho; the contents of the rare metal elements are 0.01-3 wt percent by oxidate; the lithium and
titanium molar ratio in the
lithium titanate material is 0.7-1.2; and the
titanium acid
lithium battery cathode material is produced by adopting the processes of material mixing, ball milling and sieving, high-
temperature treatment, secondary ball milling, high-temperature heat preservation and the like. The titanium acid
lithium battery cathode material containing the rare metal elements is doped with the rare metal elements, improves the quick charging and discharging properties, improves the electrochemical capacity and has excellent cycle performance, good
repeatability and high consistency; and furthermore, the titanium acid
lithium battery cathode material has the advantages of low
raw material cost, short synthesis time, low temperature, low requirements for equipment and simple manufacturing process and is suitable for
industrial scale production.
