▎ 摘  要

NOVELTY - Preparing lithium iron phosphate material involves using iron phosphate and iron oxide as iron source, lithium carbonate and lithium phosphate as lithium source, adding iron source and lithium source to a dispersing agent, adding carbon sources and additives to the dispersing agent, and then ball milling to obtain a slurry. The obtained is spray dried to obtain a lithium iron phosphate precursor. The obtained lithium iron phosphate precursor is sintered in an inert atmosphere, and crushed to obtain the lithium iron phosphate material. USE - Method for preparing lithium iron phosphate material. ADVANTAGE - The method for preparing lithium iron phosphate material in a simple, cost-effective and eco-friendly manner with relatively high performance, high charge-discharge specific capacity and better rate charge-discharge performance.
