Description

CONTEXT

Synthesis of inorganic compounds usually imply process at high temperature (ceramic, sintering) or solvothermal processes (precipitation in liquid medium at room temperature).
Ceramic processes allow to obtain polydispersed powders and are costly due to high temperature. On the contrary solvothermal process gives a better control on particle size if the steps of nuclear growth are well controlled. Yet, existence of soluble precursors can limit the range of inorganic compound available and by-products are often obtain. A supplementary step of purification is needed and these by- products must be retreated.

TECHNICAL DESCRIPTION

The invention described a new process of inorganic compound’s synthesis in ionic liquid and at low temperature.

BENEFITS

– Cost effective (from energetic and raw material point of view)
– Homogeneous particle size
– No oxidation parasitic reaction

INDUSTRIAL APPLICATIONS

Exemples of possible synthesis :
LiFePO4, Na2FePO4F, Na2MnPO4F, Na2(FexMn1-x)PO4F, LiFePO4F, NaFeSO4F, LiTiPO4F, LiFeSO4F, LiCoSO4F, LiNiSO4F, LiFe1-yMnySO4F, FeSO4F, …

DEVELOPMENT STAGE

Synthesis were made at a laboratory scale and electrochemical tests were done on the obtained powders.
