摘　　要：A new cathode material for lithium ion batteries was synthesized by sol-gel technique and tested by XRD,SEM and charge/discharge at a constant current density of 0.2 mA/cm2.The results show that Li Ni0.8Co0.18Al0.02O2 has good charge/discharge circle capability.It is a new cathode material for lithium ion batteries.A new cathode material for lithium ion batteries was synthesized by sol-gel technique and tested by XRD,SEM and charge/discharge at a constant current density of 0.2 mA/cm^2.The results show that Li Ni_(0.8)Co_(0.18)Al_(0.02)O_2 has good charge/discharge circle capability.It is a new cathode material for lithium ion batteries.
