Definitions
- the present invention relates to a process for the preparation of an iron phosphate and an alkali, the alkali possibly being more particularly lithium.
- Iron and lithium phosphate in particular is a product used in particular for the formulation of electrolytes for lithium batteries.
- this product must have a stoichiometric Li / Fe ratio as close as possible to 1.
- the iron must be present in the oxidation state II, the product having to contain the least possible of ferric ions, these ions constituting poisons in the application.
- Iron and lithium phosphate is usually prepared by a process in which lithium carbonate, ammonium phosphate and ferrous acetate are reacted at an elevated temperature (800 ° C) for several days. The product thus obtained is ground and then sintered. This process is not an industrial process because of the reaction time required and the use as starting material of ferrous acetate, the latter product being expensive to prepare. There is therefore a need for a route of access to iron and alkali phosphates which is simpler and more industrial.
- the object of the invention is therefore the development of such a process which can also lead to a phosphate having a good alkaline / Fe, especially Li / Fe, stoichiometric ratio and a very low iron III content.
- the process of the invention for the preparation of an iron phosphate and an alkali, is characterized in that a ferric phosphate is reacted with an alkali in metal form.
- the process of the invention has the advantage of using starting materials which are not expensive. It also allows working at lower temperatures than the known process with shorter reaction times.
- the invention applies to the preparation of an iron phosphate and an alkali metal.
- alkali metal is understood to mean a metal from group IA of the periodic table, this metal can more particularly be lithium.
- the main characteristic of the process of the invention lies in the choice of starting materials. Indeed, the reaction is made from ferric phosphate and alkali in metal form.
- Ferric phosphate can be obtained in different ways. It can thus be obtained by etching metal iron with phosphoric acid in the presence of oxygen. In this case, it is preferable to use metal iron of good purity.
- a ferric phosphate obtained by attacking iron oxide with phosphoric acid and then crystallization from the ferric phosphate solution thus obtained is generally carried out by dissolving iron oxide in phosphoric acid, for example 85% acid. It may be necessary to heat and if the oxide contains divalent iron, it may also be necessary to add hydrogen peroxide to the reaction medium. At the end of this reaction, a ferric phosphate solution is obtained. By diluting this solution with water, ferric phosphate is then obtained by crystallization.
- the advantage of this variant is to use an iron oxide which is a relatively inexpensive product.
- the iron phosphate solution can be diluted just before the crystallization of the ferric phosphate so as to precipitate the other metal phosphates, it is then filtered to remove these impurities and it is again diluted to crystallize the ferric phosphate.
- the ferric phosphate thus obtained is filtered and then washed if necessary.
- the variant described above optionally makes it possible to prepare a phosphate containing other ions of interest for the subsequent application of iron phosphate and an alkali. These ions can be introduced into the iron phosphate solution.
- An alkali, in particular lithium, in metal form, is used as other reagent.
- the reaction is usually carried out under an inert atmosphere, that is to say which is not capable of reacting with the alkali, for example under an atmosphere of argon.
- reaction can be carried out under conditions such that the alkali is present in liquid form.
- the reaction can be carried out at a temperature of approximately 200 ° C.
- the reaction can also be carried out under conditions such that the alkali is present in gaseous form.
- an iron phosphate and an alkali metal are obtained in which the iron has been reduced to the ferrous state by the alkali metal.
