where n is the total number of electrons reacted per mole in the electrochemical process, A is the electrode area, C is the concentration of the electrode material at the surface, and D is the diffusion coefficient. As discussed in section 3.1, the fluorinated phase begins to form at 0.2 V upon charging and the parent phase reappears at -0.2 V upon discharging. Therefore, these peaks (cathodic and anodic peaks at ~ 0.2 V, and ~ 0.2 V respectively) can be attributed to the diffusion of fluoride ions into the active material. Additionally, Figure b shows a linear relationship between the anodic and cathodic peak currents and the square root of the scan rate. This behavior is characteristic of diffusion-controlled reactions that follow the Randles-Sevcik equation. The CV measurement performed at 140 °C (Figure ) shows a reduced peak current and noticeably less sharp peaks compared to the CV at 170 °C. This outcome is expected, as the peaks are associated with a diffusion-controlled reaction. The reason behind this behavior is that lowering the working temperature reduces the mobility of ions within the material, suppressing the diffusion process. Consequently, the peak current decreases, and the peaks become less pronounced.
