Battery-grade lithium carbonate for lithium-ion batteries

This project uses the refined lithium chloride solution from a lithium chloride device without water to react with sodium carbonate, generating lithium carbonate precipitate. After washing, carbon dioxide is added to convert it into lithium bicarbonate, which is then purified. The refined lithium bicarbonate solution is heated to remove carbon dioxide, resulting in lithium carbonate, which is then centrifuged, filtered, washed, and dried to obtain battery-grade lithium carbonate. This method has advantages such as simple process, high yield, low production cost, and does not require high-temperature energy. The battery-grade lithium carbonate produced is mainly used for the preparation of lithium cobalt oxide.
