Abstract
A manufacturing method of a carbon-coated lithium iron phosphate material including steps of: (a) providing a first slurry, a lithium source, and a first carbon source having a first weight, wherein the first slurry is formed from an iron source and a phosphorus source, and the first weight is equal to an input value; (b) mixing and grinding the first carbon source, the lithium source and the first slurry to form a second slurry; (c) performing a carbon content analysis on the second slurry to obtain a loss value, wherein the loss value is smaller than the input value and greater than zero; (d) adding a second carbon source having a second weight into the second slurry to form a third slurry, wherein the second weight is equal to the loss value; (e) drying and sintering the third slurry to form the carbon-coated lithium iron phosphate material.
