Beschreibung
Zusammenfassung:	Surface modified lithium-containing composite oxide particles include base material particles of lithium-containing composite oxide, zirconium hydroxide or zirconium oxide, and at least one lithium salt selected from the group consisting of Li2ZrF6, Li2TiF6, Li3PO4, Li2SO4 and Li2SO4.H2O. The zirconium hydroxide or zirconium oxide, and the at least one lithium salt are attached to a surface of the base material particle. The lithium-containing composite oxide is represented by the formula: LipNxMyOzFa. N is at least one element selected from the group consisting of Co, Mn and Ni; M is at least one element selected from the group consisting of Al, elements of group 2, and transition metal elements other than N; 0.9
