The two graphite samples confirmed that peak displacement did not occur during the regeneration process, indicating that the graphite surface spacing of the PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC for iron removal did not change. A small peak corresponding to Li2CO3 was found in graphite, but not in graphite. X-ray photoelectron spectroscopy showed that there was a Li1s peak (55.5 eV) and a peak (289.55 eV) corresponding to Li2CO3 in graphite, which disappeared after purification and activation.
The results showed that the regenerated graphite removed the residual binder and Li salt, and significantly reduced the number of defects, which contributed to the recovery of electrochemical properties of graphite. The remaining capacity is 15%, 40%, 70% of D-LCO and its R-LCO charge-discharge curve; Magnification properties of all R-LCO and P-LCO samples; Cyclic performance of all R-LCO and P-LCO samples; Total battery rate performance and cycle performance using electrode materials for removal of iron by PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC and recycled electrode materials.
D-LCO with different residual capacity can be effectively regenerated using PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC, and its electrochemical performance is comparable to P-LCO. The magnification performance of the three regenerated LCO is similar to that of P-LCO. After 100 cycles at 0.5 C, all R-LCO samples had capacity retention rates greater than 80%.
