| Abstract: | Li -ion battery cathode materials Li （Ni1/3Co1/3Mn1/3）1 -ySnyO2 （y =0,0.01,0.02,0.05,0.10） were synthesized by carbonate co-precipitation. Its crystal structure and morphology were analyzed by XRD, SEM, its electrochemical properties were studied by AC impedance （AC） and galvanostatic charge - discharge. Li （Ni1/3Co1/3Mn1/3）0.98Sn0.02O2 had the best performance, in which initial specific discharge capacity at 0.5 C was 173.31 mAh/g, the specific discharge capacity was 149.55 mAh/g after 30 cycles, so the capacity retention was 86.29%. |
