    摘要: A method for producing a positive electrode material of Li-ion secondary batteries is disclosed. The positive electrode material of the following formula (I),Li1nullxMn2nullyMyO4nullnull(I)wherein M is Al, Cr, Fe, Co, or Ni; 0nullxnull0.4, and 0nullynull0.2. First, salts of Li, Mn and M are mixed with an organic acid to form an initial solution, wherein the mole ratio of Li, Mn and M ions in their respective salts is (1nullx): (2nully): y. Next, the initial solution is injected into a spraying chamber of a combustor to generate powders. By adjusting flow rates of the initial solution, the output port of the spraying chamber is maintained at 150null C.-200null C. Finally, the final product can be obtained by heating the powders.

    摘要: A porous catalyst support having an increased average pore size is produced from a mixed metal oxide material. In accordance with one embodiment, a method for preparing a mixed metal oxide material includes providing a mixed metal oxide precursor containing at least two metals, calcining the mixed metal oxide precursor at a temperature sufficient to form a thermally and mechanically stable mixed metal oxide material, and leaching the mixed metal oxide material in a leach solution with a constituent that dissolves one metal oxide. Preferably, the calcination temperature is approximately between 300null C. and 1300null C. The leaching constituent may be chosen from the group including acidic solutions of HCl, HNO3, H2SO4, H3PO3, and their combinations, or basic solutions of NH3, NaOH, KOH, and their combinations.
