Abstract
The invention relates to particulate lithium metal composite materials, stabilized by alloy-forming elements of the third and fourth primary group of the PSE and method for production thereof by reaction of lithium metal with film-forming element precursors of the general formulas (I) or (II): [ARRRR]Li(I), or RRRA-O-ARRR(II), wherein RRRRRR=alkyl (C-C), aryl, alkoxy, aryloxy-, or halogen (F, Cl, Br, I), independently of each other; or two groups R represent together a 1,2-diolate (1,2-ethandiolate, for example), a 1,2- or 1,3-dicarboxylate (oxalate or malonate, for example) or a 2-hydroxycarboxylate dianion (lactate or salicylate, for example); the groups Rto Rcan comprise additional functional groups, such as alkoxy groups; A=boron, aluminum, gallium, indium, thallium, silicon, germanium, tin, lead; x=0 or 1 for B, Al, Ga, In, Tl; x=0 for Si, Ge, Sn, Pb; in the case that x=0 and A=B, Al, Ga, In, Tl, Ris omitted, or with polymers comprising one or more of the elements B, Al, Ga, In, Tl, Si, Ge, Sn, Pb, at temperatures between 50 and 300° C., preferably above the melting temperature of lithium of 180.5° C., in an organic, inert solvent.
