PCT No. PCT/DK95/00232 Sec. 371 Date Feb. 14, 1997 Sec. 102(e) Date Feb. 14, 1997 PCT Filed Jun. 9, 1995 PCT Pub. No. WO95/34919 PCT Pub. Date Dec. 21, 1995A process is disclosed for the preparation of lithium secondary battery cathode active materials which are of the form LiyMn2-zM2O4 where M is selected from the group consisting of Co, Ni, Ti, V and Fe, y is in the range from 0 to 1.5 and z is in the range from 0 to 1. The process comprises forming a melt or saturated solution from manganese acetate, lithium hydroxide and water, keeping the melt/solution at a temperature in the range of 70 to 110 DEG C. for a period of from 10 minutes to 4 hours under stirring so as to form an essentially homogeneous material, and drying said material followed by calcination at a temperature in the range of 300 to 800 DEG C. |
