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.
The exceptional 93% recovery of Li 2 CO 3 at 90 °C with a remarkable purity of 99.5% was achieved by using 1.2 M ratio of Na 2 CO 3 /Li 2 SO 4. This method provides a new idea for the efficient preparation of battery-grade Li 2 CO 3. 1. Introduction
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.
A critical requirement arises for high-quality battery-grade lithium carbonate within the industrial settings. Currently, the main method for producing lithium carbonate is reaction crystallization.
The kinetic parameters and crystallization mechanism of battery-grade Li 2 CO 3 prepared by gas–liquid reactive crystallization were quantitatively analyzed through in situ tests and calculations. The feasibility of using the prepared battery-grade Li 2 CO 3 as a raw material to synthesize an LiFePO 4 cathode for lithium ion batteries was verified.
A data-gathering process (Fig. 1, box A), incorporating a literature review, was conducted to establish the parameters and variables of each process step of the routes for battery-grade lithium carbonate production.
Battery-grade Li 2 CO 3 is successfully produced. Na 2 CO 3 is added as solid and the single step recovery rate is increased to over 93%. Solid-liquid reaction crystallization mechanism of Li 2 CO 3 is elucidated through apparent kinetic calculations.
