LITHIUM DOUBLE OXIDE PARTICLE FOR COATING AND MANUFACTURING METHOD OF THE SAME

摘要

PROBLEM TO BE SOLVED: To provide an electrode material used for an electrochemical cell with improved stability against acid. SOLUTION: The lithium double oxide particle covered by one or more than two layers of alkali metal compound and metal oxide is selected from the group of LiMn2O4, LixM1yMn2-yO4, (where; M1 is selected from the group of Ti, Ge, Fe, Co, Cr, Cu, Li, Al, Mg, Ga, Zn, Ni, and V), LiNiO2, LiCoO2, LiM2yCo1-yO2(where; M2 is selected from the group of Fe, B, Si, Cu, Ce, Y, Ti, V, Sn, Zr, La, Ni, Al, Mg, Cr, and Mn), LiM3yNi1-yO2 (where; M3 is selected from the group of Fe, Al, Ti, V, Co, Cu, Zn, B, Mg, Cr, and Mn), LixWO3, and LixTiS2 (x, y are 0.9<=x<1.1, 0<=y<=1 respectively), and other lithium- containing intercalation compound.
