The invention discloses a method for preparing battery grade lithium carbonate by purifying industrial grade lithium carbonate, which comprises the following steps of: mixing industrial grade lithium carbonate with water into slurry; dropwise adding organic acid while stirring at constant speed for converting lithium carbonate into soluble supernatant liquor; adding an …
Although industrial-grade Li 2 CO 3 can be purified and crystallized several times to increase its purity, a low Li 2 CO 3 recovery of less than 75% is usually obtained, since Li 2 CO 3 is slightly soluble in water (Liu, Zhao, et al., 2021). Therefore, one-step synthesis of battery-grade Li 2 CO 3 has attracted extensive attention. Na 2 CO 3 has been commonly …
