Process of making carbon-coated lithium metal phosphate powders

摘要

The present invention provides a process for making uniform carbon-coated LiMPO₄ powders for use as a cathode material in lithium ion batteries. In one embodiment, the process comprises synthesizing a LiMPO₄ powder. The process further comprises coating a carbonaceous coating on to the LiMPO₄ powder to form a coated LiMPO₄ powder. Additionally, the process comprises carbonizing the coated LiMPO₄ powder.
