Title:

NANOSCALE PORE STRUCTURE CATHODE FOR HIGH POWER APPLICATIONS AND MATERIAL SYNTHESIS METHODS

Document Type and Number:

Japanese Patent JP2022133456

Kind Code:

A

Abstract:

To provide a method to form a lithium iron phosphate electrochemically active material for maintaining large charge/discharge current while minimizing battery capacity.SOLUTION: A formation method includes the steps of: (a) mixing a vanadium dopant source, a lithium source, a carbon source, an iron phosphate source with an iron content of at least 28 wt.% and a phosphate to iron molar ratio of 1.000-1.040:1, and optionally a co-dopant in a solvent to form a slurry; (b) milling the slurry; (c) drying the milled slurry to form a lithium iron phosphate precursor powder; and (d) firing the dried and milled slurry to obtain a lithium iron phosphate electrochemically active material.SELECTED DRAWING: Figure 1
