Charge Transfer Mechanism for Li-ion Battery Overcharge Protection — The boron and fluorine additive is in the electrolyte. When the battery is overcharged, the redox shuttle will be oxidized by losing an electron to the positive electrode. The radical cation formed will then diffuse back to the negative electrode, causing the cation to obtain an electron and be reduced. The net reaction is to shuttle electrons from the positive electrode to the negative electrode without causing chemical damage to the battery.
