    摘要： The invention relates to a method for producing lithium metal phosphates of a formula LiMPO4, wherein M is at least one type of bivalent metal, preferably selected from the first transition metal range. The inventive method consists in reacting a lithium phosphate with a metal salt and an acid phosphate source in a polar solvent for converting into a corresponding M-containing phosphate, in adding a basic lithium source for obtaining a precursor mixture for a desired lithium metal phosphate, in converting and separating the thus obtained mixture, preferably in hydrothermal conditions, in such a way that a desired final product is obtained, thereby receiving a lithium-containing filtrate. The addition of the basic lithium source initiates a lithium ion precipitation in the form of a lithium phosphate. The thus obtainable lithium phosphate can be reused in the form of a raw material, whereby said cycle enables lithium to be highly reusable.

    摘要： The invention relates to a crystalline ion-conducting material made of LiMPO4 nanoparticles, wherein M is selected from Cr, Mn, Co, Fe and Ni, in addition to mixtures thereof and the nanoparticles have an essentially flat prismatic shape. The invention also relates to a method for producing said type of crystalline ion-conducting material which consists of the following steps: a precursor component is produced in a solution front a lithium compound of a component containing metal ions M and a phosphate compound, the precursor compound is subsequently precipitated from the solution and, optionally, a suspension of the precursor compound is formed, the precursor compound and/or the suspension is dispersed and/or ground, and the precursor compound and/or the suspension is converted under hydrothermal conditions and subsequently, the crystalline material is extracted.
