Research Progress on Preparation and Modification Technology of LiFePO4

Abstract

Lithium iron phosphate batteries have excellent performance and are widely used in many fields. This article briefly introduced three commonly used preparation methods of lithium iron phosphate, high temperature solid-state method, carbothermal reduction method and hydrothermal method, and analyzed and compared their advantages and disadvantages. At the same time, it summarized some results on coating modification and doping modification research in recent years.
