LiNi0.85Co0.15-xAlxO2 samples (x=0.025, 0.05 and 0.10) were prepared by solid state reaction at 725°C for 24 h from LiOH&middotH2O, Ni2O3, Co2O3 and Al(OH)3 under oxygen flow. Layered LiNiO2 simultaneously doped by Co-Al has been tried to improve the cathode performance. The results showed that substitution of optimum amount Al and Co for the Ni in LiNiO2 definitely had some beneficial effect on increasing the capacity and cycling behavior. When increasing x in LiNi0.85Co0.15-xAlxO2, the initial discharge capacity decreased and its cyclability increased. Compromising high specific capacity...

LiNi0.85Co0.15-xAlxO2 samples （x=0.025, 0.05 and 0.10） were prepared by solid state reaction at 725℃ for 24 h from LiOH·H2O, Ni2O3, Co2O3 and AI（OH）3 under oxygen flow. Layered LiNiO2 simultaneously doped by Co-AI has been tried to improve the cathode performance. The results showed that substitution of optimum amount Al and Co for the Ni in LiNiO2 definitely had some beneficial effect on increasing the capacity and cycling behavior. When increasing x in LiNi0.85Co0.15-xAlxO2, the initial discharge capacity decreased and its cyclability i...
