In order to explore the effects of irreversible accumulation of side products on the polarization, capacity attenuation and LITHIUM intercalation of silicon carbon in PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC treatment, differential capacity curves of two groups of silicon carbon system cells before and after long cycles were compared. It can be seen that the dQ/dV curves (black lines) of the silicon carbon system cells with 3w. % and 5w. % after 50cycle are all shifted to the right, indicating that the internal polarization of the two cells increases in the late cycle.
After 50 cycles, the characteristic peak intensity and peak area of dQ/dV curve decreased significantly at 3.72V and 3.81V. It is shown that the phase transition reaction at these two potentials after 50cycle does not fully exert the capacity of PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC after iron removal, which leads to the attenuation of the overall capacity of the cell.
If carefully observed, it can also be found that the dQ/dV curve after 50cycle lacks some small characteristic peaks compared with the first cycle (red line), that is, some phase transition reactions gradually disappear with the aging of the cell, which is also one of the important factors leading to the cell capacity attenuation in the late cycle.
