The prepared Li 2 CO 3 showed uniform dispersibility and size distribution with time. CFD simulations verified the validity and rationality of the preparation method. With the significant increase of market demand, battery-grade lithium carbonate has become an imperative research.
A process was developed to produce battery-grade lithium carbonate from the Damxungcuo saline lake, Tibet. A two-stage Li 2 CO 3 precipitation was adopted in a hydrometallurgical process to remove impurities. First, industrial grade Li 2 CO 3 was obtained by removing Fe 3+, Mg 2+, and Ca 2+ from a liquor containing lithium.
With the significant increase of market demand, battery-grade lithium carbonate has become an imperative research. However, it is difficult for commercially available battery-grade lithium carbonate to simultaneously meet all criteria such as dispersion, particle size, particle size distribution, and purity.
Preparation of lithium carbonate Reactive crystallization of Li 2 CO 3 was conducted from a system of highly concentrated lithium and Na 2 CO 3 solutions. The highly concentrated lithium-containing solution was first added to the crystallizer and stirred between 2000 ∼ 8000 rpm in a high shear disperser.
To achieve a battery-grade lithium carbonate which meets a specified standard, the synthesis process was executed at a reaction temperature of 90 °C with a molar ratio of 1.2 of Na 2 CO 3 /Li 2 SO 4, and a stirring speed of 300 rpm under batch feeding conditions. This method yielded a 93% lithium carbonate with a purity of 99.5%.
Consequently, under optimized conditions, battery-grade lithium carbonate was synthesized, with an obtained lithium recovery rate of 93%, surpassing values reported in existing literature ( Zhang et al., 2019 ). Fig. 13. Characterization of battery-grade Li 2 CO 3 (a) XRD (b) SEM (c) PSD. 3.4.
