COMPOUND HAVING OLIVINE STRUCTURE, METHOD FOR PRODUCING THE SAME, POSITIVE ELECTRODE ACTIVE MATERIAL USING COMPOUND HAVING OLIVINE STRUCTURE, AND NONAQUEOUS ELECTROLYTE BATTERY

摘要

Disclosed is a compound having an olivine structure, which makes a low-cost positive electrode active material having high safety and excellent battery characteristics such as energy density. Also disclosed are a method for producing such a compound, and a nonaqueous electrolyte battery having a positive electrode containing such a compound. Specifically disclosed is a method for producing a compound having an olivine structure, which is characterized in that an iron source containing iron oxide particles, a lithium source and a phosphorus source are mixed and fired.
