After undergoing 200 cycles, the discharge specific capacity of 900 material is higher than that of 850 material, while the discharge specific capacity of other materials is lower than that of 850 material. However, the initial specific capacity of 900 material is relatively low, and the specific capacity fluctuates greatly during the discharge cycle, exhibiting instability. This is related to the structure and morphology of the 900 material, as the small particles on the surface of the 900 material cause fluctuations in the discharge specific capacity of the material.
