Research on Separation of Lithium and Titanium from Waste Lithium Titanate Materials by Dilute Sulfuric Acid Preferential Leaching AITranslate
Abstract AITranslate
Using waste lithium titanate from anode materials of Li-ion batteries as the raw material and after pretreatment,Li and Ti in waste materials were separated and recovered by dilute sulfuric acid preferential leaching process. The effects were investigated of sulfuric acid concentration, liquid-solid ratio, leaching temperature and leaching time on the leaching rate of lithium and titanium in the acid leaching process. The experimental results show that the optimized dilute sulfuric acid preferential leaching process parameters are as follows: sulfuric acid concentration is 4 mol/L,liquid-solid ratio is 6:1 , leaching temperature is 80℃ and leaching time is 4 h. Under these conditions, the primary leaching rate of lithium can reach 90%,and that of titanium is 1.08%.
