Methods for preparing amorphous ternary lithiated vanadium metal oxides and amorphous binary non-lithiated metal oxides with the formula Li x M y V z O(x+5z+ny)/z and M y V z O(5z+ny)/z respectively. M is a metal, 0 < x < 3, 0 < y < 3, 1 < z < 4, and n=2 or 3. The metal vanadium oxides are formed by aqueous precipitation methods. Rechargeable lithiated intercalation battery cells using the above materials as negative electrode active materials are also disclosed.
Procédés de préparation d'oxydes métalliques de vanadium ternaires, lithiés et amorphes et d'oxydes métalliques non lithiés, binaires et amorphes de formule LixMyVzO(x+5z+ny)/z et MyVzO(5z+ny)/z respectivement. M est un métal, 0<x<3, 0<y<3, 1<z<4 et n=2 ou 3. Les oxydes métalliques de vanadium sont formés par des procédés de précipitation aqueuse. Des cellules de batteries intercalaires au lithium rechargeables dans lesquelles les matériaux ci-dessus utilisés comme des électrodes négatives sont également décrites.
