Résumé
The performance of Li-ion batteries (LIBs) relies on the e@ective modulation of the microstructure level and the interface stability within the electrodes. Binders play a crucial role in ensuring mechanical integrity by interconnecting the active materials (AMs) with the electronic conductor additive and firmly attaching them to the current collector (CC). However, the widely used Poly(vinylidenefluoride) (PVDF) binder hasdrawbacks: low electrical conductivity requiring the addition of carbon black (CB), weak interactions with AMs & CC, and use of toxic solvents in processing. This study explores a new mixed electronic/ionicconductive polymer for replacing PVDF/CB in LIBs. It notably enhances electronic conductivity and Li+ di@usion within the electrode, facilitating faster charge/discharge rates at high current densities andforming a better interface layer promote stability over extended cycles. These promising results introduce a new binder to traditional PVDF/CB formulations.
