| titleOfInvention | Industrial method for producing battery-grade lithium carbonate or high-purity lithium carbonate |
| abstract | The invention provides an industrial method for producing battery-grade lithium carbonate or high-purity lithium carbonate. The industrial method comprises the following steps of: carbonizing; placing a carbonate-type lithium source in a hydriding reaction kettle for one time or more than two times of carbonization to obtain a wet lithium carbonate product, wherein the content of Li2O in the lithium source is 5.0-40.3% (w/w); and drying the wet lithium carbonate product obtained by one-time carbonization, thus obtaining battery-grade lithium carbonate; or drying the wet lithium carbonate product obtained by more than two times of carbonization, thus obtaining high-purity lithium carbonate. The method provided by the invention can continuously produce battery-grade lithium carbonate or high-purity lithium carbonate on large scale, is low in energy consumption and environmentally friendly and has strong practical value. |
