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.

A method of making a cathode active material comprising:
- mixing a metal precursor and a lithium carbonate powder, wherein the lithium carbonate powder comprises:
- micron-sized lithium carbonate particles;
- and
- nano-sized lithium carbonate particles coated on a surface of the micron-sized lithium carbonate particles;
- and
- heating the mixture to a peak temperature between 600-800° C. for at least 5 hours to form the cathode active material.
