Abstract
The present disclosure is directed to systems and methods of producing lithium carbonate. The lithium carbonate can be produced by contacting a lithium precursor with a carbon dioxide gas. The lithium carbonate produced from this method can include micron-sized lithium carbonate particles with nano-sized lithium carbonate particles coated on a surface of the micron-sized lithium carbonate particles.
Claims16
A method of producing lithium carbonate comprising:
- contacting a solid lithium precursor comprising lithium hydroxide with a gas comprising at least 5 wt. % carbon dioxide, thereby converting at least a portion of the solid lithium precursor to lithium carbonate.
A powder comprising:
- micron-sized lithium carbonate particles;
- and
- nano-sized lithium carbonate particles coated on a surface of the micron-sized lithium carbonate particles.
