Lithium-mixed oxide particles are coated with alkali metal compounds and metal oxides. An Independent claim is also included for the production of lithium-mixed oxide coated particles comprising suspending the particles in an organic solvent; adding an alkali metal salt compound suspended in an organic solvent; adding metal alkoxides dissolved in an organic solvent; reacting the suspension with a hydrolysis solution; and filtering off the coated particles, drying and calcining. Preferred Features: The particles are selected from LiMn2O4, LixMyMn2-yO4 (where, M = Ti, Ge, Fe, Co, Cr, Cu, Li, Al, Mg, Ga, Zn, Ni or V), LiNiO2, LiCoO2, LiMyCo1-yO2 (where, M = Fe, B, Si, Cu, Ce, Y, Ti, V, Sn, Zr, La, Ni, Al, Mg, Cr or Mn), LiMyNi1-yO2 (where, M = Fe, Al, Ti, V, Co, Cu, Zn, B, Mg, Cr or Mn), LixWO3, LixTiS2 and other lithium intercalation and insertion compounds. |
