Method for preparing lithium titanium phosphate coated with carbon

摘要

The present invention relates to a method for preparing lithium titanium phosphate coated with carbon, comprising the steps of: (a) preparing a mixed solution by adding a lithium precursor, a titanium precursor, a phosphorus precursor, and a carbon precursor to a reaction solvent; (b) preparing a lithium titanium phosphate precursor by lyophilizing the mixed solution; and (c) heat-treating the lithium titanium phosphate precursor to prepare a lithium titanium phosphate coated with carbon. The method for preparing lithium titanium phosphate coated with carbon does not need to further perform a grinding step, so a preparation process is simple.
