摘要：

Layered Li(Ni0.5Mn0.5)(1-x)MxO2 (M=Ti, Al; x=0, 0.02) cathode materials for lithium-ion batteries were synthesized by one step solid-state method using Ni(OH)(2), MnCO3, Li2CO3, TiO2 and Al(OH)(3) as starting materials. The effect of Ti and Al doping on the structure and electrochemical performance of Li(Ni0.5Mn0.5)(1-x)MxO2 (M=Ti, Al; X=0, 0.02) has been investigated. LiNi0.5Mn0.5O2, Li(Ni0.5Mn0.5)(0.98)Ti0.02O2 and Li(Ni0.5Mn0.5)(0.98)Al0.02O2 delivered 149 mAh(.)g(-1), 160 mAh(.)g(-1), 164 mAh(.)g(-1), respectively, at a current of 20 mA(.)g(-1) between 2.5 V and 4.3 V at room temperature, and. remained 86%, 91%, 91% of the initial discharge capacity respectively after 30 cycles. AC impedance studies show that Ti and Al doping in Li(Ni0.5Mn0.5)(1-x)MxO2 (M=Ti, Al; x=0, 0.02) decreased the resistance of charge transfer R., of cathode materials.
