The invention relates to a crystalline ion-conducting material made of LiMPOnanoparticles, 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.

Crystalline ion-conducting nanomaterial and method for the production thereof

The invention describes a process for producing a compound of the formula LiMPO.sub.4, in which M represents at least one metal from the first transition series, comprising the following steps: a) production of a precursor mixture, containing at least one Li.sup.+ source, at least one M.sup.2+ source and at least one PO.sub.4.sup.3&#x2212; source, in order to form a precipitate and thereby to produce a precursor suspension; b) dispersing or milling treatment of the precursor mixture and/or the precursor suspension until the D90 value of the particles in the precursor suspension is less than 50 .mu.m; and c) the obtaining of LiMPO.sub.4 from the precursor suspension obtained in accordance with b), preferably by reaction under hydrothermal conditions. The material obtainable by this process has particularly advantageous particle size distributions and electrochemical properties when used in electrodes.

Lithium metal phosphates, method for producing the same and use thereof as electrode material

The invention describes a process for producing a compound of the formula LiMPO, in which M represents at least one metal from the first transition series, comprising the following steps: a) production of a precursor mixture, containing at least one Lisource, at least one Msource and at least one POsource, in order to form a precipitate and thereby to produce a precursor suspension; b) dispersing or milling treatment of the precursor mixture and/or the precursor suspension until the D90 value of the particles in the precursor suspension is less than 50 &#x3bc;m; and c) the obtaining of LiMPOfrom the precursor suspension obtained in accordance with b), preferably by reaction under hydrothermal conditions. The material obtainable by this process has particularly advantageous particle size distributions and electrochemical properties when used in electrodes.
