Examination of Polyvinylidene Fluoride (PVDF) and Fluorinated Ethylene Propylene (FEP) as Binder in Positive Electrode of Lithium-ion Battery

The binder composition of the battery electrode can be linked to its performance in different ways as a result of a slight impact on the external properties. The binding material in lithium-ion cathode electrodes largely adds to the operation yardstick, including the cycling balance, capacity and efficiency rate, although electrochemically passive. In this study, a comparative assessment of Polyvinylidene fluoride (PVDF) and Fluorinated Ethylene Propylene (FEP) electrodes containing 5 wt% of binder in the positive electrode of a lithium-ion battery is presented. By comparing the electrochemical and physical properties of PVDF and FEP electrode binder with CES, EduPack Software generated property charts. The generated results present PVDF with properties like hardness, 15HV, tensile strength, 50MPa, compressive strength, 110MPa, density, 1780kg/m3 and price, NGN2,650 in comparison with FEP that bears hardness, 5HV, tensile strength, 21MPa, compressive strength, 15MPa, density, 2170kg/m3 and price, NGN4,900. The results serve a multifaceted purpose beyond a mere comparison but offer a deeper understanding of the consequences associated with any chosen material.
