Significance of ferroelectric polarization in poly (vinylidene difluoride) binder for high-rate Li-ion diffusion

We demonstrate the effect of PVDF polarization in lithium ion battery system. The strong polarization of ferroelectric PVDF binder on the active material enhances the transport of Li-ion during charge and discharge. As results, the Li-ion diffusion by ferroelectric phase leads to excellent rate performance and cycling stability compared to paraelectric PVDF binder.264
