Effect of Titanium Doping of Lithium-Rich Cathode Materials

The influence of Ti doping on the functional properties of the lithium-rich Li 1.2 (Mn 0.67 Ni 0.17 Co 0.15 Ti 0.02 ) 0.8 O 2 cathode material for lithium-ion batteries was studied. The oxide was synthesized by co-precipitation of the appropriate carbonate precursor followed by a solid-state reactio...

Summary:The influence of Ti doping on the functional properties of the lithium-rich Li 1.2 (Mn 0.67 Ni 0.17 Co 0.15 Ti 0.02 ) 0.8 O 2 cathode material for lithium-ion batteries was studied. The oxide was synthesized by co-precipitation of the appropriate carbonate precursor followed by a solid-state reaction. Doping 2 at % titanium in the transition metal sites increased the material energy and improved its cycling performance. Evidence in favor of positive doping effect on the kinetics of the processes occurring in the cathode material during cycling was obtained.
