However, in this paper, PTFE is used as the binder to prepare the sheet electrode material. Although the mechanical strength of the electrode material is increased, the addition of the binder increases the resistance of the electrode, reduces the conductivity, and the electrode composition is complex, which is not conducive to the electrode material. Stability, which requires further research on the forming method of the electrode material and how to improve the additive performance of the electrode material
