PRODUCTION OF SPHERICAL LITHIUM-NICKEL COMPLEX OXIDE AND NONAQUEOUS ELECTROLYTE CELL USING THE SAME AS POSITIVE ELECTRODE

摘要

PROBLEM TO BE SOLVED: To increase the density of an electrode and the energy density of a cell by using a spherical lithium-nickel complex oxide. SOLUTION: A mixed slurry of lithium nitrate and a nickel compd. is spray- dried and the resultant powdery mixture of spherical particles is fired at 550-900 deg.C in a firing furnace under continuous or intermittent fluidization to produce the objective spherical lithium-nickel complex oxide. This complex oxide is used as a positive electrode to obtain the objective nonaq. electrolyte cell.
