  • Hydrothermal process for the production of LiFePOpowder
    Patent number: 9484574
    Abstract: The present invention relates to a process for the production of LiFePO4 powder, comprising the steps: a) providing an aqueous solution of an organic surfactant; b) providing an aqueous solution of an iron (II) salt and mixing said aqueous iron (II) salt solution with an aqueous solution of a phosphate, to provide a mixed iron (II) salt/phosphate solution having a stoichiometric ratio of Fe2+:phosphate of about 1:1; c) adding the mixed iron (II) salt/phosphate solution to the surfactant solution under constant stirring; d) providing an aqueous solution comprising a lithium salt, adding said aqueous solution comprising a lithium salt to said mixed iron (II) salt/phosphate solution to provide a mixture having a stoichiometric ratio of Fe2+:phosphate:lithium salt of about 1:1:3 and stirring the resulting mixture; e) heating the resulting mixture at 80-200° C.
