| Abstract: | We report the use of Li(Ni0.8Co0.2)O2 coated with different amounts of anatase (TiO2) as a cathode material for lithium-ion cells. Electrochemical behavior is modified owing to coating and/or incorporation
of titanium into the first few surface layers of Li(Ni0.8Co0.2)O2. Compositions with molar concentrations of x=0.005 and 0.02 exhibit better capacity retention than the mother compound (40 cycles, 0.5 C rate, 2.75–4.30 V).
