Abstract
Metal chalcogenides having the general formula MZ.sub.y wherein Z is S, Se and Te; M is an element from Group IVB, VB, Mo, W, Tc, Pt, Re, Ge, Sn and Pb and y is 1.0 to 4.0 are lithiated by lithium compounds selected from LiR.sub.1, LiC(R.sub.1).sub.3, LiN(R.sub.1).sub.2, LiBH(R.sub.1).sub.3, LiR.sub.1.R.sub.2 and LiAlH.sub.4.R.sub.2 wherein R.sub.1 is a hydrocarbon radical of 1 to 8 carbon atoms and R.sub.2 is a chelating polyamine. Novel intercalated compounds of the formula Li.sub.x MZ.sub.y are formed wherein M is a Group VB element, Hf, Ti and Zr; Z is S and Se, provided that Z is Se when M is vanadium; y is 1.67 to 2.02 and x is between 0.8 and 1.2.
