Research on Process of Iron Removal from Leaching Solution of Retired Ternary Lithium-Ion Battery Materials AITranslate
Abstract AITranslate
Taking the leaching solution of retired ternary lithium-ion battery materials as the research object,the process of iron removal from the leaching solution was studied.The effects of the terminal pH value of the leaching solution after iron removal,reaction time,reaction temperature,and oxidant addition coefficient β(nNaClO_(3)∶nFe) on the removal of iron from the leaching solution of ternary lithium-ion battery materials were investigated.The optimized process parameters are as follows:terminal pH value 4.5,reaction time 2.5 h,reaction temperature 85 ℃,and β=1.1.Under these optimized conditions,the iron removal rate is greater than 98%,and nickel content in slag is less than 0.2%.The research results provide a scientific basis for the comprehensive utilization of retired ternary lithium-ion battery materials.
