Abstract: The invention relates to a method for the production of a crystal material with formula LIMPO4, where "M" is a transition metal, the method providing the steps of grinding and mixing at the solid state an organic phosphonate of a transition metal with a lithium salt and causing them to react together by pyrolysis at the solid state and high temperature by one or more heating cycles. It is thus obtained a micrometric size crystal material already containing carbon without the latter should be added thereafter. According to the invention, carbon forms inside the material during its pyrolysis directly to the surface of the lithium iron phosphate particles, interacting with the latter and ensuring an optimum electron drain.

Abstract translation: 本发明涉及一种生产具有式LIMPO4的晶体材料的方法，其中“M”为过渡金属，该方法提供在固态下研磨和混合过渡金属与锂盐的有机膦酸酯的步骤 并使它们在固态和高温下通过一次或多次加热循环热解而一起反应。 因此，此后应该添加已经含有碳但没有碳的微米尺寸晶体材料。 根据本发明，在热解过程中材料内部的碳直接形成到磷酸铁锂颗粒的表面上，与后者相互作用并确保最佳的电子消耗。
