| Abstract: |
| High-performance lithium rich manganese based cathode material Li1.2Mn0.54-xNi0.13Co0.13AlxO2 was prepared by combustion method applying cathode material of waste lithium ion battery as raw material, which realizes high-value conversion and full utilization of multi-component metal ions, and fundamentally shortens production path and reduces secondary pollution. SEM and XRD testing results show that all samples have little difference in morphology, basically spherical, with a diameter of about 0.5 μm. There is no impurity peak in samples, and all samples have hexagonal system ɑ-NaFeO2 structure, space group, with good layered structure. The electrochemical test results show that the sample with x=0.03 has the best electrochemical performance. Under the condition of 0.5 mA constant current, the first discharge capacity is 238 mAh/g, and the discharge capacity retention rate is 80.3% after 200 cycles. |
