Synthesis of lithium iron phosphate

The synthesis process of lithium iron phosphate has been basically improved, mainly divided into solid-phase method and liquid-phase method. Among them, the high-temperature solid phase reaction method is the most commonly used, and some researchers combine the microwave synthesis method in the solid phase method and the hydrothermal synthesis method in the liquid phase method - Microwave Hydrothermal assisted.
In addition, the synthesis methods of lithium iron phosphate also include bionic method, cooling and drying method, emulsification and drying method, Pulsed laser deposition method, etc. By choosing different methods to synthesize products with small particle size and good dispersion performance, it can effectively shorten the diffusion path of Li+, increase the contact surface area between two phases, and accelerate the diffusion rate of Li+.
