Hydrothermal process for the production of lifepo4 powder

摘要: The present invention relates to a process for the production of LiFePO4 powder, comprising steps: a) providing an aqueous solution organic surfactant; b) iron (II) salt and mixing said with phosphate, provide mixed salt/phosphate having stoichiometric ratio Fe2+:phosphate about 1 : 1; c) adding surfactant under constant stirring; d) lithium salt, mixture Fe2+:phosphate:lithium :1 :3 stirring resulting mixture; e) heating at 80-200 °C; f) washing precipitate remove excess surfactant, filtering drying precipitate; g) heat treating dried in inert atmosphere by firing 550-850 °C least 2 hours, wherein co-solvent is added during or after any one steps (a) (d).
